[Esa-l] How to Exempt procmail-checked mails from procmail checking

[Philip Choy]

I wonder, how to configure procmail filter, so that we can exempt the mails
that have been already checked by procmail from procmail checking.

Let us say, we have 2 mail servers, that are doing procmail filtering. It
seems that it is redundant to do checking on mails from the other one. So,
how to exempt them?

Thanx.
