I need to run a load test on a system that is processing a lot of mail.
I have the test system setup and working fine. However, with normal
incoming mail there is a lot of automated responses that are returned.
Is there a way to tell sendmail not to send any outgoing mail. It can
leave it in the queue or dump it, I don't really care what happens to
the outgoing mail as long as it doesn't go out. That would cause some
real problems.

You can use local mailbox as "smart host"
[relay for outgoing (non local) messages ]

In sendmail.mc add:
define(`SMART_HOST',`local:_name_of_local_mailbox_ ')dnl

Thanks. That works great.

For Future Readers:
It may be extended to:
* store information about envelope recipients in headers
* store received messages in 'daily' maildirs
* ...

Anyway storing outgoing messages on *TEST* system instead of simply
dev-nulling them is not a bad idea.
