Remove single recipient from multi-recipient envelope.

[Nathan Olson]

I need to remove a single recipient from a multi-recipient envelope.

I tried a ruleset, highspam.rules:
To: *@example.com delete
FromOrTo: default deliver

High Scoring Spam Actions = highspam

When a message comes in that has envelope recipients
foo at example.com and bar at somethingelse.com sendmail
creates a single queue file and a single data file.  I'd like
just foo at example.com stripped off before the message is placed
in the outgoing sendmail queue.  Currently, the whole message
is deleted.

Is this possible through MailScanner and/or sendmail?

Thanks,
Nate
