Hi, i use FreeBSD 6.0, Qmail and Vpopmail. my server has smtp auth and pop before smtp.
some users do spam on my server. i use spamguard for this people block. it is very good but spammers foxy. They use fake from name and spamguard block wrong address. For example : [EMAIL PROTECTED] is a real user and has smtp auth. He wrote from name [EMAIL PROTECTED] and spamguard block [EMAIL PROTECTED] so [EMAIL PROTECTED] has smtp auth already. i have some question about this situation 1. is it possible configure qmail blocking from names? Only @myserver.com could send e-mails? 2. this spammer use fake ip addresses so i can't detect real user. is it possible to detect real user from logs?
