Verizon has always been funky with e-mail.
I think they just started supporting IMAP a little bit ago. (If they even do yet.)
But we're not talking about Verizon email it email from Go Daddy just Verizon is the carrier and should have nothing to do with anything
They do all sorts of nutty stuff.
We use them for our corporate Internet, and it took me a few days to realize they monkey with the DNS servers they provide you. Because they return "search" results with them.
They have alternative DNS servers that funtion more like proper DNS server that have to be used. (.12 vs .14)
Anyway. my point is that Verizon does all sorts of weird stuff.

Again that's nothing to do with being at Stephen and less you choose to use theirs. They are the carrier and if you're not using their service for a certain thing and it should not be affecting anything and actually probably certain it is not in this case. If you don't use their DNS he certainly would not have any of those issues that you had
-
@BRRABill Does Verizon require you to relay email through their proxy? That would majorly suck if they did.
Sounds like they are screwing with DNS. I know Cox does the same thing, at least on the consumer side. If their DNS server can't find an answer, it returns the IP of their failure page website instead of an IP not found message.
I avoid ISP DNS servers most times. Much prefer to use Google or others.

Not through the business side of things.
And the DNS is fixable if you use a different set of DNS servers.
I'm not saying anything other than Verzion does some screwy things, so you never know what they are doing on their end.

This is all distracting from the question at hand with irrelevant information.
How to test telnetting our on port 465.

I profusely apologize to all for possibly adding any information that doesn't belong in this thread.
I know ML is built on the philosophy of keeping threads real short and tight, and never deviating from the original post, so again I apologize to anyone I offended with my three sentences.
Well, 5 now with these additional 2 sentences.
Oh no, it's now 6 ... 777 ARGH!!!!!!!!!!

@Mike-Davis said in Verizon blocking port 465 to godaddy?:
I found out that two weeks ago Verizon turned off their smtp relay, which is what set this whole thing in to motion.
Do I understand this correctly -
The old way it worked was - your email client while at your location would connect to Verizon's SMTP relay, which would then send your emails onto GoDaddy's email servers, which would then send out your email?
(it's also possible that your email client, while at your location, would connect to Verizon's SMTP relay and deliver the email direct to the end recipients server).
Did you have to enter Verizon's SMTP into the settings? Or was Verizon simply intercepting all outbound SMTP traffic and routing it forcefully through their own servers? -
But - really, as JB would say.
FFS - who cares, because SMTP is not used on port 465 normally, so Verizon's use of a SMTP gateway shouldn't affect 465 traffic.

@Mike-Davis said in Verizon blocking port 465 to godaddy?:
Can anyone suggest a test that I can do to narrow down where 465 is being blocked?
Looks like
openssl s_client -connect localhost:465Should get you a connection. If the cert appears to be from someone other than your email provider (i.e. Godaddy) then it's a good bet that that is where your issue is.
If you don't have a linux box to run this from, you can install bash on Windows 10 and run the command, worked fine for me.
I found the info over here http://serverfault.com/questions/64411/whats-the-best-way-to-check-if-an-smtp-server-is-ssl-enabled-or-not

A flowing discussion is fine, but at some point you need to get back to the question at hand or reply as a new thread and make your own topic. Additionally my opinion on where that line should be is significantly different than @scottalanmiller's.
I got stuck on a bunch of calls, but it looks like @Dashrender found the solution.

I kid, Kid.
I also originally read your post as you got stuck on a bunch of cats, which is odd.

So I went over there today and swapped out the Verizon Actiontec modem for a Ubiquiti EdgeRouter. Same results. I'm going to try the command that @Dashrender posted.
-
Have any luck with them being online? Is it just blocking port 465 still or all iNet traffic?
-
@gjacobse I got them back on line. They tried to flash the firmware on the router to see if that would fix it the problem and it reset it back to factory. They had a static IP but the factory image set it to PPPoE. Once I got the static IP settings, I got them back online. Then I decided to set up the Ubiquiti EdgeRouter to see if that made a difference.

Since this was on a windows box, I downloaded OpenSSL from:
http://gnuwin32.sourceforge.net/packages/openssl.htmopen a command prompt and CD to the folder: C:\Program Files (x86)\GnuWin32\bin
run the command:
C:\Program Files (x86)\GnuWin32\bin>openssl.exe s_client -connect smtpout.secureserver.net:465 -

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?
