I would start by searching your log files for clues as to why this message was accepted. Are you using spamfilter to send email as well as receive it? |

Thanks for your reply!
Log files show: RCPT TO: name@domain.com accepted
Why this? When I only have one domain in my Local Domain-list
(and that's not the same domain as on RCPT TO accepted)
And Whitelist Authorized TO is empty.
I send mail trough my mailserver.

Hi !
I found the problem(took a look in the mirror)!
When I re-installed the program all over again and again...,
I was in hurry because I was immediately Spammed from Korea...
So I ended up messing with one response code!
It seems that if you have wrong in your response-code(s),
SpamfilterISP becomes Open Relay.
Now it seems to work ok again...and quite effectively too!
Thanks,
Kim
