On my Linode I followed this doc to setup a mail server.
Now I can send email to any domain but can't receive from other domains!
I mean 001@mydomain.com can recieve from 002@mydomain.com but can't recieve any mail from xxx@gmail/yahoo/…com.
I checked my vmail (Maildir) too, mails from other domains aren't there.
I received Delivery Status Notification (Delay) from gmail(after about 24 hrs):
Delivery to the following recipient has been delayed:
myname@mydomain.com
Message will be retried for 2 more day(s)
Technical details of temporary failure:
The recipient server did not accept our requests to connect. Learn more at http://mail.google.com/support/bin/answer.py?answer=7720
[mail.mydomain.com. (10): Connection refused]
And it's my settings:
I have a MX Record:
mail.mydomain.com
and an A/AAAA Records:
mail (with same ip as my server)

Logs
Nothing adds to my /var/log/mail.log when I should receive other domains mail, but it seems ok when I try to receive mails by mail clients.

Nothing happens to /home/vmail/dovecot-deliver.log when I sould receive mail from other domains but in case of same domain email seems normal:

Since absolutely nothing is logged in your /var/mail/mail.log and your chains show zero traffic coming in to tcp/25, I believe your ISP is blocking incoming traffic on tcp/25. This is normal practice for home users. Unless you have a business class connection, ISPs do not allow traffic to their customers destined for tcp/25.
You'll need some type of external service like DynDNS' mailhop. You set DynDNS up as your MX and they relay the mail to your server on an open destination port like 2525.
EDIT: to be clear; real internet email only ever travels on port tcp/25. You can't just open a port like 2525 and expect it to work.
