[solved] Mail setup pop, smtp, blah blah blah

[djmega01]

I think it might be something about the ports on iptables or something.

When I try to send from Thunderbird "http://spamhaus.org/query/bl?ip=my laptop'sIP Please check the message's recipient and try again", and then I see another message saying that my server isn't accepting smtp connections.

When I try to receive, this is what I get "mailserver pop.mydomain.com responded: authorization failed"

I can't see any connection attempt on this log but maybe is because I'm new to linux and don't know exactly how to read it.
This is a little bit of what I see in mail.log
There are a lot of this lines, so I just sent you a few for you to see.
Thanks in advance.
