checkmail ValidateHost times out trying to connect with a gmail address.

When I try to use ValidateHost to validate my @gmail.com email address, this line times out trying to connect to the host. Has anyone experienced this issue before?

I'd be happy to mess around and open a PR if anyone is maintaining this library.

@kidboy-man I have not, I usually wait for some response from a repo's owner before I start working on a PR.

I’m having the same problem with ValidateHost. I’m getting the following error message:

read tcp 192.168.0.61:54120->94.100.180.31:25: use of closed network connection

If you guys are using Vultr they block 25 port by default. https://www.vultr.com/docs/what-ports-are-blocked

Somewhat related, AWS EC2 instances are blocking port 25 by default - https://aws.amazon.com/premiumsupport/knowledge-center/ec2-port-25-throttle/.
