I have to agree that this is not imo a > good thing. As I said above, trying to make your username mixed case will give you grief with e-mail. However, it's pretty easy to have an all lower case username and make your e-mail address appear in whatever case you want, so long as the system can map them back to your username in order to do final delivery. For sendmail, you'ld use genericstable to do the username -> e-mail address translation on the outgoing messages and either aliases or virtusertable to translate e-mail address -> username on the incoming stuff. Just add: FEATURE(genericstable, `hash -o /etc/mail/genericstable')dnl to your /etc/mail/`hostname`.mc (assuming you're starting by copying /etc/mail/freebsd.mc, which already has virtusertable enabled). Then create a file /etc/mail/genericstable containing: marty Marty (LHS is the username, RHS is the e-mail address: you can use the fully qualified [EMAIL PROTECTED] style if you want, or [EMAIL PROTECTED]). See aliases(5) for the syntax of the aliases file. virtusertable is just like genericstable except the columns are reversed and the e-mail address has to have an @... part: [EMAIL PROTECTED] marty Then run: # cd /etc/mail # make # make install # make restart-mta Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil. 26 The Paddocks Savill Way PGP: http://www.infracaninophile.co.uk/pgpkey Marlow Tel: +44 1628 476614 Bucks., SL7 1TH UK
