ISP is blocking port 25

First I signed up for a free DNS hosting account through Mydomain.com I registered my domain through them years ago. So I have control over my own DNS records.

Second I went to NO-IP.com and signed up for the $39.99 mail reflector account. I found a great article by them on how to set it up here :

http://www.no-ip.com/support/guides/email/blocked_port_25.html

It was quick and easy. I paid my $39.99 and added my domain name. I put in port 2525. Then I added my email alias in the place provided by their site so when they receive my mail it would not bounce.

Third my DNS MX(mail exchange) record pointed to my domain ip address, so I had to change my my record to point to the no-ip.com mail servers. I changed my MX records to mail1.no-ip.com and a secondry mx record to point to mail2.no-ip.com.

Fourth I logged in to my SME server. I went to port forwarding and set port 2525 to forward to port 25 with the ip set to the word localhost.

It worked perfectly. Here is my litte map:

Incoming Mail

Yahoo mail --> MX record check --> Mail1.no-ip.com (port25) --> My SME server (port 2525).

Outgoing Mail

My SME server ---> My ISP's SMTP server ---> World

Works perfectly.
