Hi guys!

I setup postfix - with a catchall email. When I send a email from Gmail i get it , but from Yahoo email or from Twitter for example - it get nothing. And it doesn't bounce

What does your mail log show when the mail comes in from Google vs. when you expected it to be delivered from those other providers?

When I send a email from gmail to the server example@domain.com - i get the email. When i look at the /var/log/mail.log with tail -f –- i get a full report on the connection.

If i send the email from yahoo.com or other places to example@domain.com - I dont get the email and mail.log or mail.err isnt triggered or added to at all! I wonder if its connecting to STMP ports at all!

Possible something going on with DNS/IPv4/IPv6 not set up right. Hard to know without your configs or a list of what ports are open, services listening and ports open in the firewall.
