Hi Boris!
My MX record and domain are ok (with Gandi.net).
On router (Bewan Lanbooster 2104P), I have open these TCP ports NAT: 22, 25, 80, 443.
I tell you that I don't have problem to receive public email with my SME 5.5.
When SME 6 receive an email, the server receive it but smtpfront-qmail block it. This is my smtpfront-qmail log:
2004-04-21 13:15:17.928836500 tcpserver: ok 2571 0:192.168.0.10:25 bay14-f7.bay14.hotmail.com:64.4.49.7::3874

2004-04-21 13:15:24.228763500 tcpserver: end 2571 status 0
I have try another public account via my ISP (citenet.net) and it's the same problem...
Thanks again!
