How can I define a local use with "@" in the name
useradd "bob@myname" gives error.
I "need" to have the @ sign in the name -is that possible. Silly reason - the system I am trying to send emails to the linux server has a bug. I'm trying to get around it.
@ is not an allowed character in most Unix logins
Allowed characters: 'a'...'z' 'A'...'Z' '0'...'9' '.' '-' '_'
$ is allowed as the last character but @ is not. To allow it you would need to patch everything from glibc, shadow-utils, pam, systemd and email.
@ is reserved as the identifier in an email address and many utilities will break if you have 2 @ in them.. aka user foo@foobar.net@foobar.net is going to cause all kinds of issues. and a user foo@foobar.net is going to find that many utilities strip @foobar.net and try to use the user foo.
