Dear Postfix Jedi,
I need your help to secure a new postfix server against the SPAM flooding.
Currently I have an old postfix based on an old debian server and since
some days, my server is subject to the SPAM flooding (+- 50k mails/hours).
How many of these 50K are entering the queue?
yes, in fact, all :( and now, I can't send an email to gmail or
hotmail for my customers.
This sounds like your server is sending out (relaying) this crap??
This is by far a more serious issue and you should immediately
shut-down your mailserver and check why the spam could enter the queue
to get relayed. Using RBLs does not harden your server against
open-relay/hacking abuse.

Andreas
