Now I have rebuild the entire firewall using SNAT and DNAT insteed of MASQUERADE (to prevent "wrong" packages headers to came to my server with my internal firewall address. Now everyone come as THEY are. ;-) )
BUT - yeap..a catch ..again
Still no INBOUND mail from the WORLD.
No - the world is not my clients with OUTLOOK EXPRESS.. i MEAN - GOOGLE, HOTMAIL, and what-so-ever other MTA.
I've tested it:.
From OUTSIDE !
(waited a LOOONG time for initial presentation)
220 smtp.mydomain.com.br ESMTP Postfix
helo localhost - #just to test
250 2.1.0 Ok
CONECTION CLOSED BY FOREING HOST
no "NO RELAY AUTHORIZED" error.. just DROP the connection like that?
Am I missing something?
Can I paste here my firewall script? (of course, not the real IP's been used.)
