I've done this before and have used 2525. I don't think there is a "standard" work around port. When your customers complain just say change your smtp port to 2525.

Seems Verizon is blocking port 25 for all but their mail servers. Of course, this means we're getting some unhappy customers, because all they see is our service not working. I did a little digging, and I figure it's possible to set up another qmail-smtpd instance running on a non-standard port. However, before I do this, I'd like to know if there's a semi-standard port that other people are already using. It would certainly be great to be able to tell customers "Verizon is blocking you, but here's our work-around." Thanks again. -Matt
