Verizon blocking port 465 to godaddy?

I would suspect something like the AV on the computer, but if the laptop is taken out of the network, it sends mail fine. Also on an iPhone, we reproduced the same problem. On wifi through the bad Verizon connection, the phone can't send email. If we disconnect from wifi and let it go to the mobile carrier the email sends. So it's not a Windows or AV thing.
I'm hoping if I can get an email address of someone in support at Verizon so I can email them my findings to prove it's on their network.

As for some of the back story to respond to the stuff up above about the SMTP relay. Yes, up until two weeks ago, if you were a Verizon customer, you had to put their server in your SMTP server field, and specify port 465 and SSL and a Verizon username and password. So this was not an open relay, but a way for them to see exactly what customer was sending what and how much. For what ever reason, they shut that service down and you should be able to connect to your email provider directly. That doesn't seem to be working....
I know all the settings for the accounts are correct, because as soon as they leave that particular Verizon connection, they can send email once again.

WOW, the invasion of privacy on that email service seems borderline criminal.
Is this a business connection?

Yes, static IP and all.

Cox also has a server on port 465 at smtp.cox.net I'm curious what you see inside vs outside, will it be similarly broken setup communication?

To me this is as grievous as Lenovo's actions. The BS excuse I'm sure is antispam, wow.. just wow.

Thanks for the idea to try to connect to another mail server. When I try to connect to cox from Verizon, it looks like it works:

So Verizon isn't out and out blocking 465 because some stuff goes through.
-
not that it should matter, how about openssl'ing the IP address of your SMTP server instead of the FQDN?

good idea. That would rule out any DNS stuff like suggested above. It seems they are doing some kind of DNS round robin. I queried the DNS entry on a few different server and tried them all inside the bad Verizon and none of them work.
Outside the bad network, which ever one I try seems to work.

Then I decided to set up the Ubiquiti EdgeRouter to see if that made a difference.
What was the outcome of using the ER?

That was their recommendation but not the only way. You could always run your own proxy. They have no way to block it, not universally.

I've used a Verizon business connection for years and never had to use a relay.

you can find all available IPs by using nslookup to find all MX records, then all the IPs of those entries. Should be much faster than pinging the FQDN from several sources.

ER performed the same. I put the Verizon router back in place since the Verizon router also had wifi.

It's an odd situation where what normally works doesn't and now I have to find the test to show them who needs to own the problem .
