receiving e-mail – how
it works
1. JDAEMON listens for incoming
SMTP connections on port 25
2. Messages are read using SMTP
protocol and queued to
/var/spool/mqueue
3. If the destination address
appears to be local, the aliases
database and .forward file (if
any) is used to resolve the final
delivery address
4. sendmail.cf determines the
mailer to be used based on the
final delivery address
5. Local messages get delivered by
/bin/tsmail to
/usr/mail/USER.ACCOUNT
6. Messages for remote
destinations are delivered via
SMTP
