SMTP Examples: How Does An SMTP Server Work?

Professional SMTP servers communicate using SMTP to identify each other and figure out the proper path for delivering the mail to its desired destination. When a user sends an email, it is received by an outbound SMTP server, ideally on TCP port 25, using SMTP. Once the sender gets authenticated, the outbound SMTP server analyzes it to identify the DNS server of the receiver. The DNS entry provides the SMTP server with an IP address of the inbound SMTP relay. The receiver’s SMTP server then transfers the email to its internal servers.

Understanding Outbound And Inbound SMTP relay In Brief

Outbound and inbound SMTP relays find use in routing emails between SMTP servers. The relay has less functionality than the SMTP server, and it merely obtains the nearest SMTP server and transmits the email to it. SMTP server has added features as it sends the email to a POP3/IMAP server and also filters emails.

An inbound SMTP relay additionally acts as a firewall for the receiver’s primary servers as it detects any anomalies like the wrong domain, spam, or malware in the email. An outbound SMTP relay used the DNS entries of the receiver’s domain to gather information to ensure the delivery of emails to correct destinations.
