ISP Deny's Port 25

[cdg]

I had looked into my email log because my emails were not sending, and it turns out that my ISP blocks port 25 sending of emails. Can I use a different port and how, or can I set up a mail server on a different ISP that does not block port 25?

You can let your mails be process through Gmail or other email providers. (http://vestacp.com/docs/ -> DNS Gmail template). You might also be looking for a cheap vps where mail is allowed.

You can also use port 465, 587 and 2525. Make sure they are open in iptables. Or you can use any port you want, you do nat redirect in iptables.

How do I process the mail through gmail? It is not shown in the documentation.
