Mike, Sendmail is *supposed* to run the local mailer setuid as the recipient, so procmail should have run as you. I'm running sendmail 8.13.1 on solaris 7 & 8 and it does seem to setuid properly. Is it possible that procmail itself is setuid root and is invoking the shell which is sourcing your .cshrc? It would be interesting to see a truss -f of sendmail doing a local delivery. $h is the host as set from the 2nd part of the $# local mailer rule. It probably isn't set in your sendmail rules for local users.
