The & in shell has a special meaning, it would have to be "escaped",

cd .. & ls

Means go up a directory then list it. & is a command separator or
something like that. && means execute the command that follows only if
the preceding command executes successfully.

Usernames should be A-Z, a-z, 0-9 and . _ with no other characters being
reliably passed in shell or by MTAs. That probably means list names
should be the same.

+ has a special meaning too, for VERP (variable envelope routing)
