Sendmail is going to lowercase the local part of the address before trying to match users. It isn't quite case insensitive, it accepts upper/lower in the address and wants to match lower in the passwd file entry. Adduser should have given you an 'invalid user name error', though. -- Les Mikesell lesmikesell@xxxxxxxxx
