_IMail_ doesn't refuse anything, it just sends back 5xxs for unknowns.
This  is  exactly  like the Outlook/OE/Bat client question surfaced on
the IMail list, except that full-fledged MTAs submit the messages they
can  and  kick back DSNs for the ones they can't.

Think  about  it:  this  is  why  dictionary attacks work; if a single
envelope  failure always triggered failure of the entire session, we'd
be  a  lot  safer, since spammers could _only_ use a stack of verified
addresses.
