pop3/smtp server setup questions

I was following the how to for setting up a secure relay email server.

I got to the part about using netstat to see that my services are running, and this what I see:

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 localhost.localdoma:ipp localhost.localdo:32772 ESTABLISHED 928/cupsd
tcp 0 0 localhost.localdo:32772 localhost.localdoma:ipp ESTABLISHED 1382/eggcups

this doesn't look anything like what it shows in the How To. What have I done wrong? and what is eggcups and cupsd? Have I missed a big step somewhere before I should be trying to start an email server?

I'm not sure what info is needed to figure this out, but here goes:

Operating system is RH Linux ES 3
Server is on a LAN with NAT from the router to the server's LAN IP
I have a static IP which I will be having a domain name registered to later
Webmin 1.50 used on server as well
My Linux experience is virtually nil, with the exception of running a Half-life server in the past. But I'm doing my best to figure this out.

cups is a printer daemon that connects to your printer to print stuff.


try typing "service sendmail start" as root, then "telnet localhost 25" to see if it is running your mail server.

I don't think you used netstat correctly. On a default install there will be many more ports than that bound. I think the netstat output has been piped to grep and it's looking for only established connections.

Try this:
netstat -anA inet

Originally posted by AbecX cups is a printer daemon that connects to your printer to print stuff. try typing "service sendmail start" as root, then "telnet localhost 25" to see if it is running your mail server.

ok when I did that the server returned the following

Starting sendmail:                                         [  OK  ]
Starting sm-client: sendmail: fatal: flush queue mode requires no recipient
                                                           [FAILED]

and after doing the "telnet localhost 25"

I got

Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
