my first reaction was negative, but the more i think about it, the more i
think it's probably ok. the actual case of multiple RCPT TO: recipients in
an error bounce shouldn't, i think, show up in any case involving RFC
compliant MTAs.

only issue from my point of view is that i don't think i'm seeing any spam
that fits this profile. i'll have to look out for some.
