Weird DNS issues for domains

Besides, what sort of "dumb SMTP client" did you have in mind?
Formmail scripts? Worms? Outlook Express? I can't say I'd miss mail
from any of those.

Pot, kettle...

Yours seem to have come via a train wreck of mua/mta's

spam and virus rating on outgoing is pointless nobody in their
right mind is going to use them.

I agree, all that nntp stuff is pointless too

Whilst I think it is silly to do.

Why not drop emails that claim to be viruses or spam?

Of course why anyone would allow their servers to send such is another
question.

It would be silly to believe things that said "I'm not spam", but the opposite
doesn't necessary apply.
