Uhm, no, I don't think so. This is more a question of weather to add an
option to make MailHost/sendmail fail if one reciepent is rejected or only
when all recipients are rejected as it is today. I'm still not sure it's a
very useful idea though. :-)

If you call sendmail directly without going through MailHost you will get a
list back of the rejected recipients. Maybe you could use that?
