Hello MET4LG0D
Unfortunately theres not much you can do. Most ISPs lock port 25 to prevent spam, this is becoming standard practice (and some places it's already).
99% of the servers send email to port 25, you can not control other servers so incoming email is out of question without a relay.

Outgoing email is probably possible to use another port:

Edit the file master.cf

PHP Code:

#EDIT this line:
smtp inet n – n – – smtpd

#CHANGE the smtp to your port (1234 is your port):
1234 inet n – n – – smtpd 


This will make the outgoing email use that port and might work....
