I just set up postfix+amavis+clamav+dovecot on ubuntu, moving my

can
tell, this is valid according to both RFC2822 and RFC5322.)
Trying to send to that on the smtp server gives me:
501 5.1.3 Bad recipient address syntax
Postfix handles them according to
http://www.postfix.org/postconf.5.html#swap_bangpath
Thanks! Adding
swap_bangpath = no
to my main.cf allows postfix to accept this (crazy, ill-advised) email.
However, I strongly advise against using them in an address in modern
times over the internet.
This is mainly due to the fact that you cannot control every mail
server
in the world.
Understood. This is just an alias used under certain circumstances.
