Hello,

Recently, I've found entries on my anti-spam mechanism of someone adding spam
addresses in china to my whitelist.

at first I thought it was the mechanism. However, take a look at this (this is 
a message
that got back to the senders' mailbox after the receipient was not found from 
the
actual mail server) :

Now, AFAIK, I've setup XMail in such fashion as to reject any relay attemps.
I even checked on specialized sites if I've left any holes open.
It looks fine. Still . . .

Do you chaps have any ideas why is this happening ?

I am about to backup the mailserver and re-install the anti-spam mechanism.
Something very laborious and very time-consuming.

Thank you all,

spyros
