Gmail Blacklist

As one of the most trusted email providers, Google keeps top-notch security by maintaining their own blacklist and security information. With the numerous users the company provides email accounts to, there is an overwhelming amount of data that Google can scrutinize for spam or malicious emails. By gathering this valuable information, rules are created to filter problem content. These rules are highly sophisticated, and as this data is compiled, specific IP addresses are flagged and sorted into what is called a blacklist.

The Gmail blacklist is designed to prevent unwanted spam, malicious content and excessive amounts of emails. Some of the most common reasons for getting blocked are as follows;

  • Large amounts of emails sent from a new IP address.
  • Sudden changes in email volumes.
  • High bounce rates.
  • Spam reports from Gmail users.
  • Incorrect DNS settings.
  • Low sender scores.
  • IP listing in public blacklists.

Gmail’s blacklist may also take information from several public blacklists in order to block malicious/unwanted/compromised IP addresses prior to having any complaints from them. This is a preventative measure intended to keep the lowest amount of spam possible. All things considered, this is the reason your Gmail address will likely have far less unwanted emails or better filtering rules.

 

There are several effects to being on the Gmail blacklist, and the most obvious is that all email from the IP address sending mail will be blocked. This means everything including personal communication, bulk messages, email lists, etc. Not only will it block the problem domain or user, but everything else on the SMTP server attempting to use that IP address.

This poses a large issue for shared IP addresses on any server. But there is hope! Both in the form of preventative measures as well as ways to redeem your IP address and clear it from the blacklist. Before clearing your IP address we highly suggest you review the information to make sure nothing has been compromised. Blacklists often mean an email has been hacked, or there are just poor emailing practices.

Preventatively, you can protect the IP you are using with SPF records should you have no current issues. These records will assist in providing additional verification for the IP address you are using and help keep your IP clean.

 

If you’re already experiencing issues with Gmail delivery, then the first step is to diagnose the SMTP server. If this is a managed environment, it’s best to contact your hosting provider and ask them to review the specific email address having issues. Be sure to include example messages, any bouncebacks you’ve received and any specifics you can remember. (Subject lines, recipients, time of email, etc.) This should help in the retrieval of data.

You can actually get a full copy of the headers of any messages having issues directly from your email client. If you need information on how to do this, you can always check out this article. View full e-mail headers.

If you are having trouble delivering mail and can’t find any fault on your SMTP server, then it’s time to search some blacklists to test the waters. One of the most reputable places to start is mxtoolbox.com. Although Gmail does not state what mechanisms they use to blacklist, this site allows you to search your domain and query a large number of blacklists that should tell you if there are issues coming from your server. Along with cleanup instructions and links to each blacklist, this site is a handy tool for anyone looking to admin their own email.

There are several other sites that can be referenced for blacklist checking, but unfortunately, the only one way to get information from Google specifically. If you are not on a blacklist and there are no issues coming from the SMTP server, then it’s time to fill out a Delivery Problem Form. This form asks for basic information as well as any technical information you can provide. The more information you can provide, the easier your process will become for a listing check and possible removal or de-listing.

From there, Google should help you through the rest of the process or provide further information that will move the issues along. But that still leaves us with one question….

 

Well, the guidelines differ depending on what you are using email for. As some of us just use email for personal use the rules are pretty simple. Don’t send malicious content, make sure you don’t attempt to use huge files or send to everyone in your address book every thirty minutes for no reason, etc. These are all suspicious behaviors or hard rules that will either fail or cause issues.

Really we can boil the best practices down to a few important rules of thumb.

  • Do not spam.
    • This includes redirects. Google has specific best practices for pulling email from other accounts, so setting up forwarders in other SMTP servers to shovel all mail over to Google addresses will simply count as spam.
  • Follow the bulk mail guidelines.
  • Pull, don’t push.
    • Meaning import messages or set Google to pull from third party, don’t forward to Google automatically. (Manual forwarding to share information is perfectly fine.)
  • Use SPF records.
    • SPF records are great added security and verification.
  • Change your passwords frequently.
    • Remember, passwords are vital and knowing the best practices for safe passwords is very important.
  • Watch for, and read, bounceback emails.

Following the few suggestions above will keep your SMTP server healthy and happy. When all information intended for Google is pulled via their methods, the likeliness of being blocked for false positives (meaning blocked for legitimate practices done incorrectly) will go down exponentially.

 

Change Primary Domain in WHM

If you use multiple aliases ( previously called parked domains) within a cPanel account, you may find yourself wanting to change the main domain used for the cPanel account containing these domains. Changing the primary domain is desirable for multiple reasons and many times occurs when the site in use switches from one TLD to another (i.e., .net to .com). You may desire to change this if the name of your company or site changes. It can also occur when a domain is no longer used, or when the domain is removed from an account. Sometimes the wrong site name was set to be the primary domain, to begin with (we all make mistakes, right?). Whatever the reason for changing the primary domain, the change is relatively simple to make. However, it does make some potentially significant changes on the account that could create the need for additional changes for site functionality, so it is best to understand what these changes are before making this decision wholeheartedly.

Email & DNS

This change will modify multiple factors of the domain including (if you so choose) the cPanel username (which is usually not advised), the FTP username and MySQL users. Making this change will delete any custom DNS records if you are using custom nameservers setup within WHM and hosting your DNS. If using custom nameservers be sure to go into the DNS editor and take a screenshot of your DNS for the domain or copy the records to a text document before making this change. An additional effect is that all e-mail accounts change to reflect the new domain, for example changing the primary domain from yourdomain.com to newdomain.com will change admin@yourdomain.com to admin@newdomain.com. You may then need to update the e-mail address and username (for both incoming and outgoing servers within your e-mail client) on any devices that e-mail account is set up on.

Aliases

If you already added an alias ( a parked domain which shares content) or addon domain (which has its content apart from the main domain), you need to remove it first. Meaning you may need to save the content and site data for addon domains elsewhere on the server until after this change. You will also want to remove any subdomains of your primary domain name before you can change it as well. The following can be used as a basic guide to remove these as the process for each is the same:

Log into cPanel: yourdomain.com/cpanel
Navigate to and click on ‘Aliases’ (this may be listed as parked domains on older versions of WHM) (or you could locate subdomains or addon domains)
Locate the alias you want to be removed and click remove.

SSL Certificates

If you have an SSL certificate applied to this account, you will end up revoking the SSL installed for the current primary domain by removing it. In these cases a new SSL is necessary. If you are using AutoSSL, you may need to re-run to ensure all sites have an SSL installed appropriately. If you have purchased an SSL, you will need to order a new SSL for the new domain name.

Changing the primary domain may require modifying the siteurl if you are using WordPress and this could break the installation until you change the URL.

Hostname

Often changing the primary domain is confused with the hostname of the server, these are separate changes. However, for clarity, this does not change the hostname of the server (your server name) and does not change the name of the server within your manage.liquidweb.com account either. Changing the primary domain will only change data related to the cPanel account and its associated user. While most changes are made within the cPanel account for the user, this change can not be made within the cPanel account for the domain. Changing the primary domain is done via WHM which requires root level access.

Backups

Before making any significant changes on your server, its advised to have the ability to revert in case of mistakes. Create a full website backup via cPanel for the account you want to modify. You can find instructions on how to do this here.

Ensure that you have available backups for the domain within the backup restoration area in WHM. These will be available if you already have backups configured within WHM. If you use alternate means to back up your accounts, ensure you have available backups before making this change.

To change the primary domain, you will need to do this within WHM.

  1. You can access WHM by using the servers IP followed by the port 2087, or if DNS is set up for the hostname, you can access WHM by using the hostname/whm. Another method is to use a domain name on the server followed by /whm:Examples:
    • 192.168.1.1:2087 (replace the IP with your servers IP)
    • https://hostname.com/whm
    • https://domainname.com/whm
  2. To change the primary domain login to WHM using the root user and root password:To change the primary domain log in to WHM using root.
  3. After logging the top right of your window is a search bar (you may need to expand this menu). Access List Accounts via the search bar and click on the link it displays.Find the primary domain in WHM by searching for "List Accounts".
  4. Find the user you want to modify by typing in the name of the account in the new search bar that opens. Then click the + symbol next to the user:In the WHM account click the "modify account" button to change the primary domain.
  5. Finally, click the Modify Account button:The 'modify account' button changes the primary domain in WHM.
  6. Change the Primary Domain to the domain you want in its place:WHM screen indicates where to change the primary domain.
  7. Decide if you’re going to adjust options. You could decide to modify the databases associated with the domain to include new prefixes, for example, changing the Username.
Note:
If you are not familiar with what these changes mean. It’s highly recommended NOT to change the cPanel username. Since the username is tied to the database name, you may get database errors when altering. Changing the username requires further site coding and configuration by your developer. Your WordPress or CMS configuration file will need to be updated if the username is changed creating new database names.

After making this change, you may find that you want to keep the old e-mail addresses used by the old primary domain. If this is the case, the fix is simple. Park the old domain on the new one via an alias and create new e-mail accounts under the old domain name within CPanel’s e-mail accounts section. This way you can still use your existing e-mail accounts and also change the primary domain.
