IMAP server to download from POP3 Accounts
 

My one buddy tells me that I need an IMAP server. Now that I know what it is, I tend to agree with him. And, as always, he's no help. So... I'm looking for a simple (hence the post in :newbie: ) IMAP server that I can install on my CentOS 4.1 box to download email from at least 4 POP3 servers (probably more in the future),and access it from anywhere I choose. I've had dynamic DNS set up for a while now, so that's not a problem.

Also, can IMAP be configured to send email (ie if I give it a SMTP server address, can I send mail to my server which will route it to that SMTP server)? Not that it's a big deal, it would just make my life easier if I could do that (in any given day, I'm between 2 or 3 separate networks).

As always, thanks all!

imapd is as simple as it gets.
fetchmail is used to get the email from multiple accounts.
then use sendmail to send the email

Let me see if I understand all this...

Use fetchmail to get the mail from my POP3 servers onto my linux box, and put the mail in my user's mailfile.
???
Access the mail which is now stored on my Linux box in my apartment using IMAP and dynamic dns.

What goes in the ??? area? Does fetchmail put that mail into my mailfile (/var/spool/mail/chris)?

By default, yes.

All you need is:
sendmail ( This is what is called an MTA=Mail Transport Agent)
imapd ( This is the server that will listen for imap mail clients )

fetchmail will pull your mail down from your isp.
it will deliver it to sendmail which will then put it in your inbox

then you use an imap client like pine or squirrelmail which will read your inbox and any other imap files you may have created in your /home/mail folder.
