Jerry,
Not to incite a flame war here but STMP error codes are not built to
capture the nuance that Michael is wrestling with.
As I understand it he wants his mailserver to accept the message and
quarantine it for analysis and not for later delivery and NOT deliver it
to the recipient.
It seems to me perfectly acceptable to return a 5xx as the message has
not been accepted for delivery to the recipient.

I wasn't the OP, just pointing out that option #1 was a bad idea.
Personally, I don't see enough virus mail from legit senders that I
would want to notify the sender, even with a 550 at SMTP-time. We use
scoring to (in theory) avoid quarantining the false positives from
third-party signatures.
However, for someone using the milter, 550-and-quarantine seems
worthwhile, and certainly doesn't hurt anything -- especially since (I
gather) it worked in the past.
