Use maildrop to forward a m...

I recently had the need to forward e-mail based on the from field to another mailbox. I know, it's possible with a simple .forward in your $HOME, but that will forward all the mail.

So after some further searching I end up with the following rule for your maildrop filter... it simply checks if the mail (in this example) is from linus@mail.example.com  and will forward it to linuxbox@collector.example.com:

if ( /^From: .*linus@mail\.example\.com.*/ )
{
        dotlock "forward.lock" {
          log "Forward mail"
          to "|/usr/sbin/sendmail linuxbox@collector.example.com"
        }
}

And that's all you need to put add to your $HOME/.mailfilter
