How to Troubleshoot SMTP Errors: Part 1
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 Thunderbird?

Thunderbird is one of the most widely used open-source email clients in the world. Mozilla originally developed the software in 2004, but the project waned in 2014/15, and Mozilla stated that they would only deliver security and maintenance updates in the future. Until recently, the community maintained the software when a Mozilla Foundation subsidiary, MZLA Technologies Corporation, took over. Today, the improvements in security and stability are very much appreciated, and since version 78, Thunderbird has built-in OpenPGP encryption technology enabled by default. Earlier versions used the available PGP technology, but it needed to be installed as a supplemental plugin.
