It is unacceptable! Start with "grep pwascak@aol.com /var/log/maillog". There are two entries related to that address. One entry has the sending IP and the sender address. The other entry has your server IP sending it to the destination server. Do the same for the many others! Please note that you could set your server to be secure, to only relay for the authenticated, but those authenticated users could be using weak passwords (dictionary words) and those can be cracked. Once spammers figure out one such weak password, they will use it to relay through your server. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", grep ^[^#] :-)
