Some help with canonical (and/or regexp) please

Hi,

in main.cf:

        canonical_maps = regexp:/etc/postfix/canonical-regexp

in canonical-regexp:

        /^[^]*$/ ${1}some.host.invalid

in the logfile:

        postfix/cleanup[18055]: warning: regexp map /etc/postfix/canonical-regexp, line 1: out of range replacement index "1": skipping this rule

Clearly I must be doing something wrong. Please enlighten me.

My intention is to rewrite
        "From: <friend>"
into
        "From: <friendsome.host.invalid>"

Side note:
This is because of "append_at_myorigin = yes" which I shouldn't
alter unless I fully understand what's going to happen (and I don't).

Apart from the warning not to change it, I couldn't find more information
on append_at_myorigin; I'd appreciate more info on this either.

TIA,
Alex
