Emails not sending or receiving in roundcube

SYSTEM INFORMATION
OS type and version CentOS Linux 7.9.2009
Virtualmin version 7.1

I have set up Roundcube. While Roundcube says emails are sent successfully, users do not receive them. Furthermore, I cannot receive any emails sent to my inbox as well.

This is the mail log I see. Anything I can do to fix it?

Thanks!

I see alot of timeout, log on to server and do some ping tests. I suspect the gateway address. Trace route tests as well to see where its timing out.

I see at least one deferred status in your logs. There could be a problem with your setup.
