In part one of How to Troubleshoot SMTP Errors, we reviewed email status codes, internal reasons for email issues, and troubleshooting steps to address those issues. In part two of this series, we will examine some of the external reasons for email issues. 

What is SMTP?

The Simple Mail Transfer Protocol (SMTP) is a communication protocol used to transmit email between corresponding email servers. Using an email client like Mac Mail, Outlook, Thunderbird, or web clients like Gmail or Windows Live, SMTP can send messages to an email server. Although SMTP was initially designed as an email transport and delivery system, it later encompassed the email submission protocols that are now in use by both the Post Office Protocol (POP) and the Internet Message Access Protocol (IMAP). The above-noted email clients use these protocols to retrieve email from an email server. When this system fails, it provides the means to identify and resolve SMTP errors.

What is Tmpmail?

Tmpmail is a utility written in bash that allows a user to create and use a temporary email address for receiving emails from the command-line. Underneath the covers, the bash script uses 1secmail’s API to receive the emails. By default, email addresses are created at random unless a specific email address follows the --generate flag.

What is SMTP?

When you send an email, your email client and multiple servers on the internet use the Simple Mail Transport Protocol or SMTP to move that message around the internet and ultimately into the recipient’s mailbox.

Many large ISPs restrict the access to port 25 on their networks to attempt to stem the tide of spam sent out from compromised computers.  If your ISP is restricting access to port 25 you will not be able to send e-mail through your server, but by enabling SMTP (Simple Mail Transfer Protocol) on a different port, like 26, it may be possible to circumvent the restriction.
