We have a requirement to selectively log the contents of incoming and
outgoing mail for archive purposes. I have had a play with sendmail.cf,
and have come up with the following:

In the mailer definition for the different mailers, I change the P field
to the path name of the logging program. The logging program can then
examine the "To:" and "From:" lines in the header to decide whether this
particular mail item needs to go into the archive. It then invokes the
mailer that originally was mentioned in sendmail.cf, e.g. /usr/bin/uux,
sending the message on stdout.

This works fine for the local and the uucp/ACSnet mailers because they all
expect the mail on stdin. However, for mail that is forwarded by our 
gateway to other local machines via the ethernet, the mailer specification
uses P=[IPC]. From the sparse documentation, it seems that the IPC mailer
actually opens a well known port to get the mail, using SMTP.

The question is, can anyone tell me how I can examine mail that is sent
through the local ethernet for its contents and selectively log it somewhere ?

Thanks a lot in advance for any help,

					Michi.
