pop3 server confusion
 

Ok, I have some kind of pop3 server running, but I'm not even sure which (which makes it hard to configure). I'm running Debian Lenny (64 bit) and have installed sendmail and openwebmail. I did a 'locate pop3 >> pop3.txt' and the only config files or directories with pop3 in the name was for openwebmail.

I was having trouble even connecting to it at first, as it gave the error: 'password was rejected' but it also said "failed to create /var/spool/pop/.username.pop with uid ####, gid 0"

So I changed the group of that /var/spool/pop directory from mail to root and the pop access seems to work now (it also worked when I made /var/spool/pop writable by all users and that's obviously not a good idea).

Any ideas on how I can find out what is handling pop3 so I can configure it?

EDIT

btw, I don't think the openwebmail is handling the pop3

A pop3 server by default should be listening to port 110 so if you do a:

Look for something that is listening on port 110. The -p for netstat will show the app that has the port open in the far right column.

Perfect, that's exactly the kind of solution I was looking for but never would have thought of trying. This reveals the program is inetd which I know is a wrapper program to increase security. I'll check the inetd configuration file...

in.qpopper which is apparently configured by qpopper.conf

Thanks!
