I'm getting the error that I could not open a socket with my Google Apps SMTP service.

I'm using these settings:


This is my stack trace:

I've noticed (sometimes) in my mail.log for Postfix that connections to Gmail times out and it requires a resend.

I don't have Postfix installed on my webserver, I'm assuming that it's done through XenForo?

Nope. Postfix is an MTA that is installed at the OS level.

Nope. Postfix is an MTA that is installed at the OS level.

So you're saying that I need to have Postfix installed on my webserver for XenForo SMTP emails to work?

No, what I'm saying is that I have observed timeout connections in my mail.log from Postfix sending to Google. The nice thing is since it's an actual MTA it retries till it sends or errors out or connects - but doesn't lose the message after just one attempt.

I'll double check, but I'm fairly certain we're using TLS for GA mail usage.

Edit:
TLS with port 587, standard config for us. (Your server needs OpenSSL installed as well...)
