Where does linux server/postfix store what it does with email messages that don't make it to the mailbox

Not sure how to troubleshoot this problem, but have a user that can not receive emails from a specific domain (can from others) and the outside user is not receiving a bounce message.. my question is how can I determine if the email ever actually reached the server? Is there a log that would have that information in it?

Logs are usuallty stored in /var/log.  There should be a postfix directory under there with the various log files.  The SMTP log should show you if the message was received.

I don't see anything for postfix at all, here is an ll of the log directory (I removed the repetitive gz files)

You can look in the maillog folder, or it might be storing it in a custom location.

/usr/local/var/log, or even in the postifx directory /usr/local/postfix/logs or something similar.
