Port 25 is open by default.

What do you mean "does not work"?

iRedMail opens several network ports by default, and 25 is one of them.
Is port 25 open in iptables? You can verify it with command 'iptables -L -n'.

Well in my outlook express I can not use port 25 or the mail spam server I have on different machine can not connect via 25 because we get an error saying auth is not correct on server.

Re: I need to open port 25 but cant figure out where to open it at

here is what I get:

root@mail:~# iptables -L -n
Chain INPUT (policy DROP)
target     prot opt source               destination

Chain FORWARD (policy DROP)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

this is what I get in outlook:

http://i40.tinypic.com/swg0et.jpg

when port 110 and 25 are on and SSL/TLS is on none.

now when I switch it back to 995 for incoming and leave port 25 alone still getting same error message about SMTP cant connect.

Now this is the logs when I use webmin:
