Port 587: SMTP Command Timeout - closing connection

This is weird, but I'm hoping someone might be able to point me in the right direction: I have two emails from one of the domains on my server that are timing out. They have one recipient in common. When I try to force send it from the queue, I get this result: R=lookuphost T=remote_smtp defer (110): Connection timed out In researching the problem, I was led to check port 587 through telnet and when I did that, I got this message: SMTP command timeout - closing connection I can't find much help on how to get past this point. Does anyone have an idea? Thanks!

  remote_smtp defer (110): Connection timed out means the remote server is either down or your servers IP is blocked there is nothing you can do you do not know if the remote server is listing on port 587 (unless its your server) you should check the default port 25

  Hello :) Another step you can take is to try connecting to that remote server over port 25 from another server to see if it's blocking all connections or just connections from your cPanel server. Thank you.
