The attached patch adds a trust_from_address option, which is basically the
opposite of fix_from_address. If set, then each user's configurable From
address is used as the SMTP envelope sender (if possible), and the user's
authenticated username is placed in an X-header. It builds on
usernames_with_at.patch.

(Also, as a bugfix for usernames_with_at.patch, if the authenticated username
contains '@', return_domain is no longer appended.)

This is analogous to Exim's untrusted_set_sender option, and Postfix's
default behaviour.

With a patch attached this time...

(The patch is in the right format to add to debian/patches directly.)

thanks

Even if we can trust the users not to use forged sender addresses, I think we
still need to sanitize the input before passing it to the shell.
