If I remember e-mail basics correctly: No. They're not. For example, f...@example.com, f...@example.com and f...@example.com and all upper/lowercase variations are the same as f...@example.com. For sending mail within a system and across systems, names in the passwd file have to be in conjunction with the respective mail queues for the users. Even "foo" and "Foo" can coexist (as soon as they have a different UID, reflecting the fact that two distinguishable users are intended), but regarding mail... that sounds problematic. > Without fighting an epic battle with with the sendmail configs, is > there a simple way to make this work?

As you mentioned correctly, usernames with uppercase letters may already appear in config files. You _could_ check for each user below his $HOME for any appearing in a file and replace this, but that could cause trouble if something is stored in a "Registry"-like binary file. Regarding /etc/passwd, the home directory _may_ be a different name than the username, so those _pathnames_ in files should not require a change. But files mentioning _usernames_ will probably cause problems. > How can I enable mail for > them?
