I'm interested in learning how to run e-mail off my linux router connected to the internet, I already run apache for my friends and was wondering what would be the best way to set up e-mail accounts. I want to be able to have multiple users and multiple domains, with logins not related to linux users and passwords. What would be the best way to do this (and provide IMAP and/or POP3/SMTP to users to get their e-mail) ? Links to manuals and instructions would be helpful, thanks!

Well, looks like you want a virtual host, MySQL, Qmail/Postfix and Courier-Imap tutorial

http://www.postfix.org/docs.html (the Pop IMAP section)
A link from that page:
http://kirb.insanegenius.net/postfix.html

Also, I suggest looking at Qmail, it's very secure, and comes with a pop3d included:
www.qmail.org
And for setup, this is the most often referred to site:
www.lifewithqmail.org

Cool

See the link in my sig below for a great tutorial on setting up Postfix with Spamassassin. It rules..

since you are already using apache you might want to try openwebmail

ok, i set up qmail, i can send e-mail out to anyone on the internet, but i can't receive e-mail from anywhere on the internet. I get this:

This message was created automatically by mail delivery software.
A message that you sent has not yet been delivered to one or more of its
recipients after more than 24 hours on the queue on varsity.vosn.net.

The message identifier is: 19b2J7-0002o5-1u
The date of the message is: Fri, 11 Jul 2003 11:07:49 -0700
The subject of the message is: Incoming!

The address to which the message has not yet been delivered is:

psx-dude@secondangle.com
Delay reason: Connection refused

No action is required on your part. Delivery attempts will continue for
some time, and this warning may be repeated at intervals if the message
remains undelivered. Eventually the mail delivery software will give up,
and when that happens, the message will be returned to you.

could it be i'm blocking the port or is qmail blocking it? (I have 110 and 25 open)

if you can connect to it using telnet on port 25 it's listening for connections

telnet secondangle.com 25

if not it may be not lestening for connections or it's blocked by a firewall


try this to see if the mailserver is listening

netstat -lnp | grep :25

is the hostname valid? try it with ip address
