Setup POP Mail Accounts
 

Hey guys,
I have been doing some research lately and I currently have not been able to find much help. I have got over 50 website's hosted on my server and am now curious on how to setup POP Mail Accounts for each domain. Do you guys know how or can show me how I can setup POP mail accounts on my server please? I am on RedHat 9 Thanks and have a great day!

how can you tell if your computer uses POP or SMTP?

How does this even remotely help the user? If you have your own questions, as them in your own threads that you can start.

Like our rules state, post constructively or don't post at all.

And besides, POP is a way to retrieve email, SMTP is way to send email.

richhoward,

A quick search on google.com/linux: http://www.google.com/linux?hl=en&lr...p+pop+accounts

Comes up with many results. It all really depends on what app you want to use to setup with, like fetchmail, etc.

sorry my question is phrased wrong!

if i may say my question the way i wanted to...

i dident post it to BOOT my post amounts!!! i admit that my question that i wanted to ask would not benifit the LQ member but i wanted to say something like this.

Regarding POP and SMTP mail servers, how can you tell which one your moail account uses is POP for incomming mail and SMTP for outgoing?

Sorry if the post was not constructive.

i did not realise how it was phrased and i know, read before you post, check, etc.......

Well again, you should also post your own questions in your own threads. Hijacking others threads to ask questions isn't considerate, especially when your question really has nothing to do with their question.

Well, you need to install a mail transfer agent (MTA) and a POP server. However, IMAP is better than POP, so I'd consider using IMAP. If you have a lot of users POP is going to eat up a ton more bandwidth. From the user's perspective POP pretty much sucks. POP ties you to one computer, IMAP allows you to see your email from anywhere. (This is oversimplified, there are exceptions, etc..) If you run POP be prepared to have this conversation quite often:
user:"A bunch of my mail disappeared! This is terrible and you must fix it!!!"
you:"Did you check your email on a different computer than usual?"
user:"Yes."

Well, the messages were all downloaded to that computer and deleted from your server.

MTAs are things like sendmail and postfix. Postfix is easy to set up. You'd just configure it to accept mail for all fifty domains. Pretty simple. It is also your SMTP server, so when users send mail they connect to port 25 on your box.

IMAP servers are programs like cyrus, courier-imap, and others. I've never set one up.

I don't know any POP servers, but I'm sure google will provide.

You might need to also use procmail, which is used to filter and sort mail.

You'll probably also want to run something like Spamassassin, which works with procmail.

Here's a five part series on setting up a mailsystem. It's IMAP, and its for a home user, and he uses his ISP email account to collect mail, but it is still useful for the basic concepts. Collecting your own mail is trivial, your MTA does it for all domains tell it about.

Here's another five part series on integrating spamassassin into your mailserver. You want this:

Mailsystems are very modular; lots of little programs that do specified tasks. I run a mailserver just for the people in my house. We don't need POP or IMAP service (because we either check email at home or use SSH on the road). Anyway, my mailserver works like this:
Fetchmail (fetches mail from IMAP accounts at ISP and gives it to Postfix)
Postfix (accepts mail from fetchmail, accepts mail sent directly to our server, sends mail)
Procmail (accepts incoming mail from Postfix and gives it to Spamassassin)
Spamassassin (filters spam then gives mail back to procmail for final delivery)

So it works like: incoming mail->fetchmail->postfix->procmail->spamassassin->procmail->inboxes

For you it'd be like:
incoming mail -> postfix -> procmail ->spamassassin ->procmail -> inboxes

And postfix would accept SMTP connections from your users and send their mail
And some IMAP or POP server would accept connections from your users to let them view their inboxes.
