Hi all !
All of a sudden my server stopped accepting emails tonight !
I tried to connect to the admin console but it was throwing undecipherable content (firefox asked to open "octet-stream" content".
POP and IMAP work fine, as well as the webmail !
I tried to send an email to myself via an external account.
The smtp transaction worked fine (I checked via SMTP Check - Pingability.com because my ISP blocks pour 25, so I cannot test it from here), but the mail got bounced :
This is the Postfix program at host mydomain.com.

The Postfix program

Connecting via ssh worked, but a "zmcontrol status" showed everything was up and running !
I've restarded all services but it did not help. I've rebooted the server but it still doesn't work !
I don't know what to check next !
I am absolutely not an expert in linux, so I am quite lost...
I almost forgot the important part :
Fedora Core 4
Thanks for helping !
