mailscanner only sees the envelope TO

[Ken Anderson]

MailScanner only looks at the envelope TO address, so if your mail
server allows messages to have 100 recipients, you have 99 users who
can't control what they perceive to be their own email filtering. :-(

What is the best way to handle this issue?

So far, we've limited the MaxRecipients in sendmail.cf to 10.
Users don't send mail out through our MailScanner boxes, so this works
reasonably well, since less than 1% of incoming mail is actually
addressed to more than 1 user.

Thanks for any ideas,
Ken A.
