Every email I try and verify times out and then fails. Can't figure out what I'm doing wrong

Here is the output of the debugging:

Other things of note:

I had a lot of trouble getting dnspython installed. Maybe its running, but not actually installed properly? It seems to work when I do a simple socket.gethostbyname_ex() though.

Hunter.io has no problem verifying the email address:

This seems to me that hostname resolution works, but google is blocking port 25 requests from your original IP address as well as VPN address.

To check, you can try and telnet to port 25 of any of those addresses listed above. In windows, this would be:

  • opening a commandline window (win+R, cmd, enter)
  • typing telnet ALT1.ASPMX.L.GOOGLE.com 25 and see what gives.

Oh, I forgot you have macos. There, the command specified above has to be run from within a terminal window.

You were right --- it was my internet provider and my VPN that are blocking port 25 access. Interestingly, when I use my phone as a hotspot its fine.

Can you recommend a VPS or VPN that doesn't block port 25?

Not really. I use zenmate but I never tested it with this. I have my own servers for when I want to test.

Well, I'm trying AWS's free tier right now and can't for the life of me
figure out which setting I'm missing. We'll see what their support says. If
that doesn't work I'll try zenmate. Either way I'll report back.

Thanks both for making this and for being so responsive!

AWS blocks port 25 in egress, it has been mentioned here somewhere in the closed issues. if you search for it, you'll find it.

Update: Got it to work on AWS, just needed to ask them to open up port 25
(when asked why and what I would do to prevent spam abuse I was honest and
told them I wanted to use this package and would just turn off the instance
when not using)
