I routinely test with .forward files containing

    username

or

    usernamelocalhost

Not a problem. The \ prefix forces mailbox delivery and can't loop.

However, "mail forwarding loop" means the mail with delivered-to
is delivered again to the same address, so you *do* have a genuine
mailer loop.
