If they're going to play SMTP Football, and run sendmail, they need to put the following in their sendmail.mc files: define(`confMAX_HOP', `32')dnl or even higher. If they can't figure out how, or can't be bothered, your best defence is a small shell script that does this: ##!/bin/sh echo "Removing user $1 from all lists due to mailer idiocy" lcmd quiet del "*" $1 mail -s "Your removal from our lists" $1 < canned.maxhops exit 0 and put some useful text in canned.maxhops. ;) /Valdis (who used to be liberal in what he accepts, conservative in what he generates, but has gotten trigger-happy in his old age ;)
