Guess what kiddies, in troubleshooting an email connection for a customer that was unable to send any email through one of my servers, I found the problem was not quite what I expected. The good news is that the problem wasn’t my mail server, or even on my end at all for that matter. After some testing and digging I found that the problem is that Verizon has now blocked ALL out bound port 25 traffic. Period. As you know, port 25 is the standard RFC compliant port for SMTP communication, and Verizon has blocked all port 25 traffic as a means to fight SPAM. Uh-huh. Sure.
This means that you cannot use any other email provider for sending mail unless they support a non-standard port for their SMTP service, or you are using webmail exclusively. This, to me, is wrong on so many levels. First off, it’s not helping in the SPAM wars as far as I can tell. I am told the same thing by some Verizon customers I surveyed. Second, it’s just wrong to cut out basically all other mail providers like that. This is yet another example of how stupid Verizon is, and how they cannot manage their service at all.
I have done business with many, many telco’s over the years, and Verizon tops the list by a mile of the worst service providers to deal with. Some of the most incompetent people, bone headed mistakes and plain batshiat crazy experiences have all been at the hands of Verizon. I hope this is just the first of many nails in their coffin.
One last thing, conveniently enough, the only way around this is to upgrade to FIOS (or other non-specified broadband service) and pay extra for a static IP address. How nice. Read more here.
I agree completely with you about verizon. I have placed 6 orders for DSL with them in the past 3 months. Verizon canceled them all. I live in a 1/2 mile stretch between 2 houses that have DSL service and am told that I cannot be provided service. “Some of the most incompetent people, bone headed mistakes and plain batshiat crazy experiences have all been at the hands of Verizon.” pretty much sums up my feelings.
