Hello, I am quite new to Ubuntu (2-3 weeks), after Windows 7 crashed I formatted everything and decided to move to Ubuntu.
In order to setup a mail server, I setup Postfix and Dovecot following this (https://help.ubuntu.com/community/MailServer).
I can send emails, but I can't receive them (from gmail or hotmail for example). I use Squirrelmail. I can auto-send emails via Squirrelmail.
When sent from outside, nothing appears in mail.log.
I did try telnet emailing and it worked.
I use port 587 (uncommented "submission inet n - - - - smtpd") because it seems that my ISP blocks port 25.
SMTP is from my internet provider.
MX Record is: guytremblay.com priority 10
Weird thing is when I do SMPTP test on MX Toolbox (http://mxtoolbox.com/) I get the following:
8/26/2013 12:08:43 AM Connection attempt #1 - Unable to connect after 15 seconds. [15.04 sec]
