I would expect the ISP to bounce it, so any legitimate sender knows
there's a problem. We're talking business users here, so HTML emails
with animation and audio attachments are not an issue. Sending Office
documents in active form carries a risk, and business people should be
aware of this. If you have real problems, have your ISP pass everything
and deal with it yourself. I don't see spam/virus checking as a
significant factor in an internal/external decision.

Why would that happen? All mail servers distinguish between local and
external email. Nobody was suggesting dropping Exchange and just using
Outlook in POP3/IMAP/SMTP mode.

It will take up more space. So delete it or save it off-mailbox after
reading. You should be doing that anyway. It's what mailbox quotas are
for.

You, of course. Have software warranties suddenly sprung into existence?
Who do you sue if your own virus checker misses one?

IRC. Email isn't instant, nor was it ever intended to be. If you want
instant delivery of packets you use UDP, not TCP, for the same reason.

Indeed so, and in my opinion the gains from in-house email for myself
and current clients are totally outweighed by the disadvantages. Should
I acquire a client where the trade-off goes the other way, I will advise
accordingly.
