Sendmail/wrappers question
whats the surest way to prevent mail hosts with no reverse dns from being able to connect/send email? The hosts.allow example seem more accurately ident'ing and refusing than check there is a reverse dns. Any insight is appreciated! :) ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
