Thanks for your reply,

yes this works with aliases and that aliases can contain uppercase-
letters, but that was NOT my problem.
I have several users and unfortunately the usernames are already build
containing uppercase-letters. So i need to work with the existing
password-database and i have to make sendmail to accept this usernames.
Again: i want sendmail to accept usernames with uppercase-letters that
       already exist and are real entries in the passwd.

Again any help is highly appreciated.

Bye, Darius.
