So I was trying to set up an email server and I ran into a snag when I realized that port 25 was actually being blocked. I didn't think much of it until I realized that many big ISPs actually block port 25 by default.
I figured, oh I'll just call my ISP and ask them to unblock port 25 for me. No dice. I have to have a business account with Videotron to actually get my port opened. Even though they claim you have to have purchased the package for static IP etc, I've had the same IP since I got this one. Can't they just go ahead and let me have that port opened?
Anyway, I don't want to spend an exorbitant amount of money just to get a port opened, does anybody know how to get around this?
Do you have any other open ports? You could just change the port your email server runs on.
Other than that VPNs or SSH tunnels
Or host your email server on Rackspace, AWS, something similar.
If you just change the port on the server from 25 to 26. Let's say I send you a mail, there's no way for me to know your server listens on port 26 and not 25, so you won't receive any of my mails.
You need a service that redirects incoming traffic from port 25 into another port.
For example https://www.dynu.com/en-US/Email/StoreForward
Or just set it up on AWS or something.
also your IP is most likely blacklisted so no one will receive emails you send out.
That too.
@OP your ISP won't open your port 25, unless you buy a business account. So yeah.
A free smtp redirection service is offered by http://ghettosmtp.com, but you know, it's free, so they could do all sorts of things.
I'm assuming 587 is blocked as well?
Edit: Was there anywhere in your agreement that ports would be blocked forcing specific services not to work correctly?
