How it goes is like this...
There's prorams that "run in the background" on Linux. Relative to mail,
we have SENDMAIL, SMTP, POP2, POP3, and UUCP.
Sendmail is a router, nothing more.
SMTP is a "forwarding agent" - Is that a good description ?
Simple Mail Transport Protocol
POP is Post Office Protocol.
To make some analogies, sendmail is like the guy in the back room of the
post office, sorting mail into this bin or that bin. SMTP is like the
mail man, he picks up mail from the post office and delivers it to other
mail-men, or other post-offices, he also can pick it up from the mail box
and bring it back to the post office. POP is like a P.O. Box, you have to
go to it to get your mail.
Does that help ?
POP has no way to accept mail from a user and forward it to another. It
retrieves mail only.
Try "telnet localhost pop-3", then USER (yourloginname) <enter> and
PASS (yourpassword) <enter> and HELP <enter>. See what you come up with...
You can also "telnet localhost sendmail", and "telnet localhost smtp".
Then you can manually type to each of these programs and really really
get a feel for how they work.
Also, why do you ask ?
