ValidateHost times out trying to connect with a gmail address. #26

Open DCtheTall opened 5 years ago

DCtheTall commented 5 years ago

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.

hi @DCtheTall have u solved this issue? I also encountered similar issue when ValidateHost, the error message I got is Code: dia, Msg: dial tcp 74.125.68.26:25: i/o timeout

Same as I, I got this error message back Code: dia, Msg: dial tcp 74.125.195.27:25: i/o timeout

@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/.

When I connect on public WiFi, I get this issue, but I do not get the issue when I connect from my office. It can be an ISP issue if the port is open/closed/throttled.
