Mail server and port 25
Posted: Tue Oct 19, 2010 4:38 am
Hi,
Ok, I am trying to setup a mail server on my local server but am having some problems which I think are due to port 25 blocking but I want to make sure.
The domain I have will be example.com and all of the webserver stuff works just fine, I have ssh, http, virtual desktop, all working just fine and dandy. The problem comes with dovecot and postfix. I setup both of these and it seams to be going well but I can not get outside emails sent or received. I have the server at home and at work I connect to it with Thunderbird, this seams to go well. From work on Thunderbird I can send myself emails from the same email address, they show up in the inbox no problem so at least it seams like things are setup properly.
The problem comes with trying to send an email from an outside domain to that email address. If I send from gmail to the same email address that I have setup on my server then it just bounces for like 2 days then cancels. If I try to send mail to an outside domain from the server then it does nothing and the mail.log just gives errors like this:
Would these problems all point to the block or maybe I am doing something wrong with the configuration?

so I am leaning to "my isp blocks port 25". I have port 25 pointing to the correct server and whatnot, I just can not connect to it.Oct 19 12:29:30 shiznatix-server postfix/smtp[6786]: connect to alt3.gmail-smtp-in.l.google.com[74.125.67.27]:25: Connection timed out
