Description Benjamin LaHaise 2007-05-21 12:48:09 EDT
Attempting to create a user with the userid foo@bar.com via adduser is rejected
as being an invalid userid.  Userids with @ in them are required for hosting
applications where mailboxes for many domains are hosted using dovecot,
saslauthd and postfix.  A simple patch to accept these ids is attached.

I'm sorry I can't accept this change. usernames should follow POSIX standards 
or at least some RHEL conventions. You can propose this change on fedora-devel 
mailing-list and if there is some consensus about it, I'm free to commit the
