Re: [northeast] Important Changes to Your Email Service -

said by NormanS:

Test and verify that their service is working on port 26. Once you have done that, it won't bother you when Verizon finally throws the switch.
Wow, if that's true (that I can use 26 instead of 587), that would be great. Thank you. Port 26 works fine now, I just wasn't sure it would work after this change.

BTW, I never received any notification of this, and neither have a number of neighbors on FIOS. Seems silly of them to spring this on us; I wouldn't have known about it if I didn't read this forum.

I haven't either.
Maybe it's an area by area thing.

Port 587 is defined by RFC 4409 as the standard "Message Submission" port. However, email service providers are free to use any port unlikely to be blocked outbound for message submission.

The problem is that port 25 can't be made to require authentication for email service SMTP relay between services. Maintaining an authentication database by each provider for each other provider would not scale.
