An internet protocol used for sending and relaying email messages between clients and servers. It is not designed for convenient mailbox access; for that, IMAP or POP3 are typically used.
Why it matters
Every sent email passes through SMTP. Understanding response codes helps distinguish temporary issues from permanent address rejections.
What's missing without it
Without a working SMTP, the system cannot send notifications, newsletters, or payment reminders.
When it is used
During email sending configuration, bounce diagnosis, and email address verification.
How we use it
CMS sends activation emails, publication notifications, or task error alerts.
