Cannot telnet to server on port 25 (sendMail, dovecot, firewall?)

[dlite922]

I'm a linux n00b, but i know enough to find my way around and not cause mayhem.

With the help of online tutorials and someone else who knows just a little more than me, we've managed to install sendmail and dovecot? ssl-auth.

But don't know if everything is installed right.

I can telent localhost 25, but when doing the same from WITHIN the LAN, it does not work.

I can't forward my firewall to that server yet, because well duh that will put my email server offline. (Win XP with hMailServer)

I'm a PHP developer and can get a killer LAMP runnin, but this mail stuff is driving me nuts.

What commands should i issue for you guys to help me out? Where do check for my firewall rules?

I'm semi-sure I disabled SELinxus. (or chose not enable it at Install)

Thanks in advance,


Dan

you should check your firewall rules first. You can see them by doing iptables -L
or specify a category: iptables -L INPUT

But there are some nice tutorials online about that.

You could also check on what address the mailserver is listening just do
netstat -lnp | more

if it says something like 127.0.0.1:25 then you know your smtp server is only listening on the local host and you might have to reconsider your configuration file.

I hope this helps out a bit
