help me with Mail Server
Hi,
I download CentOS ServerCD and Install it into my Server.
I configured the Named and Squid, but I have problem with the Mail Server.
I configured, but the User (with Windows using IncrediMail, Ms Outlook or Outlook Express), send Conection Refused.
I tried to look:
telnet ns.cervegsa.com.ni 25 (where cervegsa.com.ni is the domain)
but send me, Conection Refused, too.
Could some body helpme
Thanks.
Pd.: Exuse me my english, my native language is Spanish.
God Bless You

Re: help me with Mail Server
Did you open port 25 in iptables?
If uncertain, post the output from iptables -L.

By default, sendmail on CentOS doesn't listen on port 25 even if you have port 25 open in the firewall.
Make sure the "sendmail-cf" package is installed.
You have to edit /etc/mail/sendmail.mc... find the line that says "DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl", and comment it out by prepending dnl to the line, changing it to this:
dnlDAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
Run "make -C /etc/mail" to create the new sendmail.cf from sendmail.mc
Then do "service sendmail restart".

Re: help me with Mail Server
BTW, I think there is a similar configuration issue with postfix, if that is the MTA you happen to be running.

Hey, thats no fair! You gave away my next response. :-D
Actually, I figured my next response would be run system-config-securitylevel-tui.

Sorry....
The reason I was quick with that answer was that it bit me before I learned about it. I would "telnet localhost 25" and sendmail would answer. I would "telnet server 25" from outside and it wouldn't. I would check the firewall, yep, I had a hole for 25. Still didn't work. Shut down the firewall... STILL didn't work... etc... etc.... :lol:

Re: help me with Mail Server
Read some documentation ? here they are : http://www.centos.org/docs/4
Sendmail/dovecot are really easy to configure (in a simple network at least) .... just follow the docs ..

Re: help me with Mail Server
i would suggest postfix as your mta. very easy to maintain and configure.
mine now is running with mysql and with webmail and pop3 access...
for a postfix jump start.
