I need SMTP relay installed Program that does not use port 25.
My customer is in the middle of nowhere and our only ISP is Verizon. I have a Smarthub in place providing the internet. By default, Verizon blocks the outgoing smtp port 25 and will not unblock it. I am looking for a program that I can install on a pc at the site that can act as a smtp relay service but NOT use port 25. I need to relay the messages through that PC from a legacy iSeries. So a webservice smtp relay program does not help me. Anyone dealt with this before?
Using a system behind a port 25 blocking ISP as a primary mail server isnt practical. You need to use a smart host, which is another system to relay mail for you.
Sendgrid.com has a free smtp relay service that offers a number of port choices for up to 100 emails a day, and a cheap plan for more.
We also use Godaddys legacy email relay service, which offers several alternative ports.
Suggest you just use a relay provider that supports a secure connection and use port 465.

Gary's comment supra is apposite. Outgoing port 25 traffic is problematic on many ISPs. I have the same problem and now I relay out through smtp2go.com, which is free for any reasonable number of outgoing emails and something like $0.002 each for over the limit.

"I need SMTP relay installed Program that does not use port 25."
Easy to do + likely not useful.
You can setup an MTA to send to other SMTP servers using any non-25 port.
And other SMTP servers listen for connections on port 25.
So you can setup this up easy + your server won't be able to talk to any other server.
Likely what you're really require is using port 587 authenticated submission through a relay server like MailGun.
With MailGun, first 10K messages/month send free.

There are some old apps that only send on port 25. This means that the simple idea of an external smarthost on a different port won't work.
I have used a number of redirect methods in the past to get around this.
Here's one option, using an MS IIS SMTP server to send via Gmail.

You could replace Gmail with any suitable smarthost you like.
