I created an /etc/postfix/aliases file containing: jim123: JIM123 Then I ran "newaliases", but it did not seem to work. I can try procmail, but I am also new to procmail. Yesterday I used procmail for the first time, and was able to divert mailing list emails in to subfolders. This required me to create a .procmailrc in my user account. Are you suggesting a "global" procmail script that would put the emails in to their appropriate user directories? I assume I could not use local procmail scripts, since my problem is I cannot resolve the lowercase username. One good thing is, this is for a closed internal system that will rarely change. The users are going to access their email using Squirrelmail w/Dovecot on Ubuntu. Since the existing users are use to seeing there names in uppercase, I want to preserver that throughout the system.
