I'm already splitting multiple recipients at the MTA level using queue
groups, but I'm interested in what you are doing. Can you post your
changes to or I like the idea of whitelisting
at the MTA level. It would save MS/SA some work.

Also, it would be nice to put messages that are sent to multiple
recipients and ARE split into single recipient messages by sendmail into
lower priority mailscanner queues, since 99% of them are spam. When a
MTA is configured to split messages, and it gets hit by 1000 x 10 recip
per messages spams, it tends to put quite a load on the system as they
are all expanded to 10 x 1000 messages, scanned and deleted or quarantined.
