As of right now, my server will not send any emails. They all seem to get stuck in the queue. Now, I do have my domain names routed through cloud flare. However, on my previous box running Cpanel, this was not an issue.
The only way email sent works correctly, is if I connect via smtp.gmail.com with my credentials.
On a side note, I noticed my box which is only a month old, for at least a few days, was appearing to be a open relay for emails. In fact, so many, that the cpu usage was starting to spike. I stopped postfix and the issue went away. After making a few changes, like turning on auth for smtp, and turning back on postfix, it seems like they're not connecting anymore.
So, first, is there any extra steps I need to perform to get smtp emails working?
Secondly, the issue with spammers getting in my box, are there any extra steps I can take to make sure this will not happen? Is there a check list of Best Practices for locking down your server?
Thanks,
James
