It seems like you could do something ala RFC 1137 for 8bit characters on inbound addresses (if you don't support them) before they get processed much by sendmail and rewrite them back on the way out of your network. Yes, it's ugly, but it's simple and doesn't require support from the mail user agent as MIME does. Anyone more knowlegable want to trounce this or have the time to hack it together? :-) -Robert -- Robert Dana <bob@worldcom.com> (713) 650-6522 x40 UNIX and IP Network Specialist, Sendmail Guru in training Wolf Communications, Houston, TX Go WorldCom!
