Mail server daemons: sendmail, qmail, postfix, exim, mmdf,
smail, zmailer etc.
The server daemon usually has 2 function:
• looks after receiving incoming mail
• delivers outgoing mail
The server daemon does not allow you to read your mail. For
this you need an additional daemon (POP, IMAP, etc).
The DNS and its daemon “named” play a large role in the
delivery of email.
