I’m able to send out email to Gmail, etc., without a hitch. But when I try sending an email from my Gmail to my server, it doesn’t work. I don’t get any messages on /var/log/mail.log so I’m not sure what’s going on.

Thanks!

Shouldn’t it be delivering to my /Maildir?

Looks like it’s delivering to command: procmail -a “$EXTENSION”

This it my ufw status:

And I just realized that I had set the master.cf file to listen to port 2525 a few days ago. So port 25 wasn’t being listened to. I set it to listen to port 25, and all the pending mail came in through the mail queue. But strangely none of them went into my mailbox. I wonder if SpamAssassin filtered them?

This is what I’m getting in /var/log/mail.log:
