Amazing. Now everything is through and said ... .

Do we agree on some basics here ? Does RHEL eventually start popa3d by 
default ? can you do some 'ps ax | grep pop' before and after you start it ?

And then, what does "I can connect via command line" mean ? what do you 
type ? Be specific, please !

Did you try to telnet from the client (the one you run Thunderbird on) 
to the server ?

What distro does the client (the one running Thunderbird) use ? Also 
RedHat ?
It might help you could install nmap on that machine and then issue some 
'nmap -v' (replace with the IP of the 

And add the 'some things from popa3d' for us to see, please !

That sits on another sheet of paper. root is the correct user to execute 
popa3d for the time and purpose being.

I don't know about RedHat, but it doesn't need one, basically. It 
'knows' what to do: read from the mail-spool on request on port 110.
