You can edit an email account that already has been configured in Mail, for example should you decide to switch between non-SSL and SSL settings or update the password.

Note: You cannot edit an existing email account to switch its account type from POP3 to IMAP or vice versa. To change the account type, you must add a new email account of the desired type (POP3 or IMAP). Adding a new account with a different connection type should not require you to delete the old one in most mail clients.

To avoid data loss, please use caution any time you change an email account’s connection type or delete an email account. Removing an email account from a mail client also will remove all messages associated with it on the device and, specifically in the case of POP accounts that are not configured to retain mail on the server, there may be no way to recover those messages. If you have any doubt or questions, please contact Heroic Support® for guidance.

Since any changes must be made on both the incoming and outgoing servers, updating the email account’s password or switching between non-SSL and SSL settings is not as simple as toggling a single setting, but the steps are easy to follow.

Step #1: Configure Incoming Server Settings

  1. You set the incoming mail server in the Internet Accounts preferences pane. To access it, select Accounts from the Mail menu.
  2. On the Internet Accounts preferences panel, select the name of your email account from the left pane to update the password or change the incoming server name or connection type.OSX 10.11 Incoming Mailserver
  3. Update the Password
    • To update the email account password, enter the new password into the Password field in the Internet Accounts preferences pane.
  4. Change the Incoming Server Name or Connection Type (SSL/non-SSL)
    • Click the Advanced button at the bottom right of the Internet Accounts preferences pane to edit the Hostname via a popup panel.
      • SSL settings will use the server’s hostname (e.g., host.yourdomainname.com)
      • Standard non-SSL settings will use the domain name (yourdomainname.com or mail.yourdomainname.com).
    • Once you have changed the Hostname, click OK.

Step #2: Configure Outgoing Server Settings

  1. Select Preferences from the Mail menu to open the Internet Accounts preferences pane, then click on the account in the left menu.
  2. On the Account Information tab, locate the Outgoing Mail Server (SMTP) row and select Edit SMTP Server List from the select menu.

  3. Change the Outgoing Server Name or Connection Type (SSL/non-SSL)
    OSX 10.11 Account Information

    • Click on your mail server’s name in the top pane to select it, then change the Server Name on the Account Information tab to the desired value.
      • SSL settings will use the server’s hostname (e.g., host.yourdomainname.com)
      • Standard non-SSL settings will use the domain name (yourdomainname.com or mail.yourdomainname.com).
    • Once you’ve changed Server Name to reflect the desired connection type, click on the Advanced tab to configure SSL settings.
      OSX 10.11 Advanced Account Settings

      • Port: This should remain 587 regardless of connection method.
      • Use SSL: If you are using secure (SSL) settings, ensure that the Use SSL box is checked. If you are using standard, non-SSL settings, Use SSL should be unchecked.
      • Authentication should be set to Password regardless of connection method.
      • Both the User Name (full email address) and Password fields should be filled out. You can update the email account password by entering the current password into the Password field.
  4. Your email account will start using the new settings as soon as you click the OK button.

 

Setting up an Email Client

Setting up email in a client such as Outlook or Mac Mail on your cPanel server for the first time can be a bit complicated, but once you know a few key pieces of information, you can get almost any email client up and running quickly.

While each program’s setup process is going to be slightly different, the cPanel email settings below will apply to Outlook, Mac Mail, Thunderbird, Android, iOS Mail, or any other email client. You can access the specific cPanel email settings for your domain and learn how to set up specific email clients at How To Set Up Any Email Client.

Secure (SSL/TLS) Connections

  • Both the incoming and outgoing servers will use your hostname (the server name, as opposed to the domain name): host.yourdomainname.com
  • IMAP Port: 993
  • POP3 Port: 995
  • SMTP Port: 465 or 587 (the latest versions of popular mail clients such as Outlook and most Apple mail clients may require you to use port 587 for SMTP)

Standard (non-SSL) Connections

  • Both the incoming and outgoing server names will be your domain name: mail.yourdomainname.com (or simply yourdomainname.com)
  • IMAP Port: 143
  • POP3 Port: 110
  • SMTP Port: 25 or 587 (the latest versions of popular mail clients such as Outlook and most Apple mail clients may require you to use port 587 for SMTP)

Authentication Is Required for All Email Connections

  • Regardless of whether you’re using a secure or standard connection, please note that authentication is required for IMAP, POP3, and SMTP. This typically is configured in an email client by a checkbox such as “This server requires authentication”. If you have such a setting, it must be enabled.

A Closer Look at cPanel Notifications

In recent updates, cPanel has modified some of the notification settings for their control panel. As a result, you may find that the priority of certain notification types have changed and you may begin to receive notifications that you previously had not encountered. In particular, the notification options for Security Advisor changed with the release of WHM 56 on April 26, 2016.

The notification changes by cPanel are meant to both help users better manage their servers and also keep them informed of potential security risks, such as those posed by outdated software versions which no longer receive updates.

With some exceptions, many of the notifications are purely informational and not necessarily a cause for alarm. Here are the most common notifications followed up on via support requests:

‘New security advisor notifications with high importance’

WHM’s Security Advisor routinely performs a security scan on the server and alerts you to items it considers potential security risks. For each item flagged, the cPanel notification will clearly explain how to resolve the issue at your convenience. It’s important to note that while some recommendations, such as enabling SMTP Restrictions, Enabling Brute Force Protection, and increasing Password Strength Requirements are worthy of attention in nearly all cases, other recommendations may not be appropriate for your situation. For example, you may prefer not to disable root SSH access or SSH password authentication (and should not unless you have set up and tested SSH keys to connect to your server). To learn more about specific messages, visit our article on cPanel Security Advisor Notices. If you need guidance, feel free to contact Heroic Support®.

‘Your SSL Certificate is now available for download and installation’

Beginning with WHM version 56, cPanel now includes a free signed SSL certificate to cover the hostname (and only the hostname) of the server on which it runs. This feature eliminates warnings and notices associated with using self-signed SSL certificates and protects all connections to server services, such as email and ftp, and is automatically installed and renewed when possible. In order for the automatic installation to occur, however, the server’s hostname must resolve in a browser (that is, it must have a DNS record). Additionally, if you already have purchased an SSL to cover your hostname (either a dedicated SSL or a wildcard) cPanel will not attempt to overwrite it. Only self-signed SSLs installed on the server services (cPanel/WHM, FTP, SMTP, and the Mailserver) will be overwritten. Only if you have a purchased SSL installed on the hostname, and allow it to expire, will cPanel replace it. In any case, no action should be required on your part unless automated installation fails. In that event, you may contact Heroic Support® for assistance.

‘The system will automatically switch the mail server from Courier to Dovecot … in order to continue receiving updates.’

In cPanel/WHM versions up to 11.52, users were able to choose between two mail servers: Courier and Dovecot. Courier was selected by default, and most cPanel users never had reason to switch. However, beginning with cPanel/WHM version 54, Courier has been deprecated. cPanel will no longer support Courier in future releases, and the control panel can not be updated until the mailserver is switched.

If you want to switch the mail server yourself, you can follow our guide. Should you prefer not to switch to Dovecot and would like to continue to use Courier, you will need to change your cPanel update preferences and select the LTS (long-term support) release tier. cPanel will continue to send daily emails until one of these two actions have been taken. If you do not take any action, cPanel will automatically switch the mailserver at the time indicated in the email.

‘The server has POP3 before SMTP enabled’

This means that SMTP authentication is not being strictly enforced on the server. Effectively, any user who has successfully logged in to receive mail is treated as authenticated to also send mail from the same IP address for an hour after their successful incoming login.

The important thing to note is that it allows the IP address from which a successful email login was made to access the SMTP server, not just the specific user or device from which the successful login was made. In a modern home or office environment, a single public IP address typically is shared by many devices on that network. That’s also the case when you’re connected to a public wireless network, such as at a local coffee shop or shopping center.

With POP Before SMTP (also referred to as POP3 Before SMTP) enabled, it’s possible that a malicious user or compromised device connected to the same network — regardless of how well-secured your personal computer, workstation or mobile device may be — could relay mail through your server. Mitigating that potential security risk would be the primary reason for disabling POP Before SMTP on your server.

However, you should be aware that disabling POP Before SMTP means that any email account would be required to use SMTP authentication, and that would need to be configured in each individual mail client used with each email account in order for the account to be able to send mail.

While all modern mail clients such as recent versions of Outlook, Mac Mail and Thunderbird and any recent smartphone have that ability, the setting may not be enabled by default. If that’s the case, the account configuration would need to be adjusted in the email client.

For assistance configuring email clients, see How To Set Up Any Email Client.

‘The server has unmonitored services’/’The service has failed’

Through its ChkServd service, cPanel is able to monitor enabled services and automatically restart them when necessary. This is separate from, and unrelated to, Sonar Monitoring services which you can configure in your Manage dashboard.

While this is not a new capability, cPanel recently began notifying users of it, along with a list of any enabled cPanel services which were not configured already for monitoring. It is recommended, though completely optional, to enable monitoring for all active cPanel services to improve stability and ensure that services can be recovered as quickly as possible. You can enable monitoring in WebHost Manager at Service Manager, under the Service Configuration section in the left menu.

One thing to keep in mind is that cPanel will alert you to any service it has found to be down and automatically restarted via ChkServd, even if the service intentionally was stopped, such as during an update or a required restart of another service upon which it is dependent.

What that means is that you should not immediately assume the worst any time you receive a “Service Failed” or “Service Recovered” alert from cPanel. If you receive only a single notification of a service restarted, and not multiple alerts for the same service over an extended period of time, there generally is no cause for concern. However, should you receive multiple such alerts for a service, or should the alert indicate that the service could not automatically be restarted, please do not hesitate to contact us so that we may investigate.

‘Altered RPMs found’

While the message subject can sound somewhat ominous, it should not automatically be cause for alarm. Typically this message is generated when cPanel performs an update check and discovers that local files are out of date, have become corrupted or have been updated outside of cPanel. Occasionally, it also can occur when both the 32- and 64-bit versions of a service have been installed.

This message will contain the filename of the package it found to be incomplete, corrupted or otherwise broken; running the command referenced in the message (/usr/local/cpanel/scripts/check_cpanel_rpms –fix) should result in it re-downloading the file successfully.

Please note that anytime updates are pushed to your server outside of cPanel, for example when an important security patch is applied to multiple servers simultaneously, this notice also can be triggered. The issue can be easily rectified by updating cPanel’s operating system packages, which support is happy to help with if you’re unable to run the command specified in the cPanel notification.

‘The cPanel & WHM update process failed’

WebHost Manager/cPanel by default checks for updates to its control panel each day. Due the number of servers running cPanel, there can be times when too many servers are checking in with cPanel’s update server simultaneously, causing the request to time out. And occasionally, the cPanel update server itself may be unreachable.

Whenever that happens, cPanel will alert you and automatically try again the next day. You can, however, manually force it to check for updates (and automatically install the update, if one is available) should you prefer not to wait.

You can find instructions for manually updating cPanel at How To Upgrade and Patch cPanel and WHM.

Should a manual update also fail, or should you receive consecutive update failure messages, please do not hesitate to contact our Heroic Support® team.

‘System integrity checking detected a modified system file’

The default notification preferences beginning in WHM/cPanel version 54 can cause this notification to be sent immediately following an update to cPanel/WHM itself.

This notification may alert you to “FAILED” md5sum comparison tests on any server software (and usually on several components at a time), but should not immediately be cause for alarm.

The server message is triggered any time a core file is changed, and makes it clear that it may be the result of an OS update or application upgrade. If you have automatic updates enabled in WHM, have manually updated cPanel/WHM, or have requested that it be updated for you, then you can safely ignore this message. If you don’t have automatic updates enabled and have not recently updated cPanel, please do not hesitate to contact our Heroic Support® team.

Disabling cPanel Notifications or Changing Alert Settings

You can configure settings for all the cPanel alerts you receive in WHM under Contact Manager in the Server Contacts section of the left menu.

The first tab, Communication Type, allows you to set the alert level that will trigger a notification to each of the communication methods: AIM, email, ICQ, Post to a URL, Pushbullet, or SMS.

The second tab, Notifications, allows you to set the minimum priority for each type of event, such as Service failures (ChkServd), Unmonitored Services, or Backup Successful, which will trigger a notification. You also can disable notifications for each event type using the dropdown menu under the Importance category.
 

Is the Server Down? I Can’t Log in or Connect

Are you unable to connect to your cPanel server to send or receive email, log into cPanel or WHM, or make an FTP or SSH connection?

Are you able to view your website in your browser? If not, and the connection simply times out, it’s possible that your IP address has been blocked by the server’s firewall. Typically, this is the result of too many failed logins (through cPanel, SSH, FTP, email, etc.) in too short a period of time.

To confirm whether that may be the case, you can test your site via a web service such as Down For Everyone Or Just Me (enter the URL of your website into the search field on the page) to see whether the site appears down for everyone else, or try to visit your website via another network, such as from a phone or tablet over its cellular connection after disabling wifi on the device.

If an IP block is suspected, it can easily be removed. If you have a Dedicated, Storm, or VPS server, and your server is running the CSF firewall, you can unblock the IP address directly from your Manage dashboard. If not, we can log into the server on your behalf, search the firewall for your IP address, and unblock it. Similarly if you’re able to confirm that your IP is not blocked, we can search the server logs for any specific errors associated with your connection attempt, or investigate any possible network issues between your physical location and the server’s that could be preventing you from accessing it.

To speed up that process, when opening a ticket, calling, or chatting in with your support request, please try to include your public IPV4 IP address (which you can obtain here) so that a support technician can help resolve the issue as quickly as possible. Please also include any error messages displayed in your browser (or email, FTP or SSH client) when attempting to connect.

Most Common Support Requests

As you might expect, most support requests on managed cPanel servers fall into a few basic categories. What you might be surprised to discover is that many common problems can be resolved by following a few simple steps.

None of the common cPanel support requests listed here are server-critical issues that require an experienced system administrator to troubleshoot and resolve, and we recognize that many of our customers are curious about their servers and actively engaged in learning more about cPanel server administration.

To that end, we’ve gathered together some of our Most Common Support Requests, and we’re sharing them with you here — along with their solutions.

Should you find yourself experiencing one of these common issues, you’ll know exactly what to expect when contacting our Heroic Support® team. And while you certainly are welcome to try to resolve the issue yourself, remember that we are here to assist you 24 hours a day, seven days a week, 365 days a year.

These articles should hold the answers to a number of common questions and, if you are so inclined, provide you with the tools and resources to resolve some non-critical issues on your own.
