Then your real problem is not with tcpserver but with spam :-) > FreeBSD 4.0 running on stock standard Intel platform Sendmail build ESMTP > Sendmail 8.8.7/8.8.7; Is there any particular reason that your FreeBSD 4.0 is running 8.8.7 version of Sendmail? Unless I am mistaken, the 4.0-RELEASE version of FreeBSD had a much newer version with the base system. (I think it was version 8.9.3 that came with 4.0-RELEASE.) If there isn't a serious reason why you are using 8.8.7, why don't you try to upgrade Sendmail instead ? I know that Sendmail can be used with hosts.allow and hosts.deny files, but this will not solve your problems with spam. If you want to do serious anti-relaying control, I think you need at least version 8.9.3 of Sendmail. Not that it cannot be done with these earlier versions too, but it is a lot easier to manage in 8.9.3 or newer. - giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
