MAIL FROM:<brong at fastmail.fm>
250 2.1.0 ok
RCPT TO:<bb+shared.foo>
250 2.1.5 ok

With:

postuser: bb

In imapd.conf.  That seems to be what the docs recommend.  It looks like
you're just using a naked "+mailbox at domain"?

I'm a little confused.  Can you show me the config and how it's supposed
to work?
