hardly. just someone who has tried blocking traffic to dialup pools with DST port 25 and forced relay on all outbound traffic with DST port 25. it worked... for some values of worked. as most would know we broke smtp-auth for a small handful of people that were trying to use it. as joe pointed out to me privately RFC 2782 specifies SRV RRs which could be used to point an MX.SRV at a port other then 25. anyone got any examples of MTAs or MUAs that implement said RFC? marty -- My Everest is not in Nepal, She's sleeping in the bedroom second right down the hall.
