How Receiving Mail Server works
-
Dear, I torn my hair since last 7-8 days to know the working of receiving mail server. The word "Receiving Mail Server" might sound confusing to you in the first instance. So let me first make you clear on that. Complete Mail service works as follows: 1. We wend email using a MTA (mail transfer agent) like "sendmail" on Linux or "Outlook" on windows. 2. Both these MTA deliver email to the SMTP server, which further delivers the email to the destination. 3. Let say we are sending email to "munendra@mydomain.com", SMTP must connect to the domain "mydomain.com" on some TCP socket, and there must be some service listening on the server "mydomain.com" to receive the emails. I want to know what this service is?? On what port does it runs?? This stage is what I mean to say the "Receiving Mail Server". POP/IMAP comes secondary after the email delivers on the server, their primary function is to fetch the email from server to the local computer. Thanks a lot in advance!!

Your outgoing SMTP server will forward onto a receiving SMTP server. From there it could be forwarded onto another SMTP server, or put into a mailbox or database for download by IMAP, POP3 or webmail. How it does that depends on the specific software and how it is set up.
