Question Allowing connections to IMAP server?


Greetings, everyone. New sysadmin here - experienced with old flavors of UNIX but still trying to find my way around Fedora Core 5.

My server came with FC5 pre-loaded and qmail was configured already with Courier IMAP. I'm running qmail and vpopmail with Squirrelmail webmail client.

Squirrelmail uses IMAP and is functioning properly. I can Telnet to IMAP port 143 when I'm logged directly into the server via SSH but something is preventing connections to 143 from remote locations... and therefore, I can't use IMAP to remotely check email on my server. It doesn't appear that I have any kind of firewall running on this server, but I could be wrong. IMAP is configured to run on startup so it's not being executed by xinetd.... I'm at a loss.

Any tips on where to begin looking?

Thx!

Hi, welcome to LQ!

One thing to look at is iptables -L ... maybe there's a rule blocking it.
Another option is to check with netstat which interfaces are making use
of that port. Maybe your qmail only listens on 127.0.0.1.


Cheers,
Tink

Thanks Tinkster. Appreciate the tips. I looked at netstat and it does show

Code:
Proto Recv-Q Send-Q Local Address               Foreign Address             State

tcp        0      0 localhost:imap              *:*                         LISTEN
I'm assuming this means imap is only listening locally. Where can I look to change this? Is there an imap config file somewhere that I'm not finding?

Cheers!
