Verizon blocking port 465 to godaddy?

Dashrender

@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:465

Should 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

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!!!!!!!!!!

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 find this post distracting and unnecessary.

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.

gjacobse

@Mike-Davis

Have any luck with them being online? Is it just blocking port 465 still or all iNet traffic?

Mike Davis

@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.

Mike Davis

Since this was on a windows box, I downloaded OpenSSL from:
http://gnuwin32.sourceforge.net/packages/openssl.htm

open 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

Mike Davis

on a machine outside of that particular Verizon connection, I get:

on a machine inside the the problem verizon connection, I get:

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.

Mike Davis

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.

Dashrender

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.

Dashrender

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.

Dashrender

Then I decided to set up the Ubiquiti EdgeRouter to see if that made a difference.

What was the outcome of using the ER?
