Dear Ulrich, I guess it couldn't be denied by DENIED_IP_IN_RDNS because s0106000625a2b407 is not hexadecimal representation of IP address. I pick may be wrong example there are partially regular reverse DNS too where sender and recipent are same like:
May 6 09:35:03 fw spamdyke[27053]: ALLOWED from: @domain.cz to: @domain.cz origin_ip: 95.48.168.162 origin_rdns: jum162.internetdsl.tpnet.pl auth: (unknown) Thanks to your answer to another thread I got idea how to block these messages. I could put our domain in sender-blacklist-file and it will definetely stop all messages containing SPAM with fake sender from our domain. Users using another mail server for outgoing mail and that mail will never reach perimeter SMTP server where SPAMDYKE does run. Thnak you! Eduard "Ulrich C.
