It's called reply_transport, and it applies only to forwardfile, because
alias files can't generate auto replies. Note that this is for Exim 3,
which is what the book describes.

Er, the "mail" command is concerned with generating a message. I'm not
sure what "mode" you are talking about. Messages don't have modes.

Alias in the DNS? That is, are we talking about a CNAME here?

Is this also running Exim?

Exim does not canonicise domain names, but some other MTAs do, which is
why I asked if this third server was running Exim. (The RFC 821/822 mail
standards specified canonicisation, but this has been taken out of the
new 2821/2822 documents.)
