Well, i must say that i have a lot problems with the specific case:
I have some customers that use one conection from my ISP and that
conection have just one IP, ok... i use this line on my /etc/tcp.smtp:
192.168.0.1:allow,RELAYCLIENT="",RBLSMTPD="",MAXCONNIP="2",CHKUSER_RCPTLIMIT="50",CHKUSER_WRONGRCPTLIMIT="2"
(let's assume that IP)
Ok. Then... if some of those customers get infected by some virus, they
send to my server large amount of e-mails, i can't block the ip, because
i'll block about 40 or
maybe 50 customers and i can't block one specific user, because the
virus changes the user all the time like:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
And of course i can't block the hole domain.

Is there anyone with the same problem?

If I got it right, you receive spam from external host claiming to be

Wouldn't this be a case for SPF checking?
