I have a strange mail problem. I can send mail just fine, I can receive from Gmail, Yahoo, mail.com, fastmail (basically all webmail clients I have tried), but cannot receive mail from other hosts (custom email addresses). Plese note that I'm using Gmail with Thunderbird and it works.
I'm tailing /var/log/maillog and I receive no error when sending from custom host, it's just like the mail doesn't even hit my mail server. And no error mail returns to sender either. My leafdns also looks ok, scores 100%:
