[9fans] How to over ride /mail/box/bwc/headers file with Acme/Mail?

[Brantley Coile]

I put `From: bwc@prepaynt.com' for example right after the To: line
in the Mail window in acme, but both that and the From: line from
the headers file in my mail/box directory shows up.  How to I keep that
from happening?  Or am I the odd man again?

Thanks

You can't override /mail/box/$user/headers.  They're always added.
I'm surprised that both showed up in your mail.  Acme Mail used
to rewrite From: as To: (to handle the case where you reply by
just editing the original message and click Post).  I thought it
still did.

I used to use the following pipefrom to change my From: line
on outgoing mail based on who it was going to, so that for
example mail to anyone at *.mit.edu would be from rsc@mit.edu.
This generally reduced confusion for receivers, and it was much
easier than having to change my From: address in every message
(like I used to do with mh on Unix).  I haven't found a good way
to do this with my current mail reader (thunderbird on Unix) so
now all my mail says rsc@swtch.com.

If a message was being sent in reply to another message, the script used
the To: address on the original, assuming it was one of my aliases.
This worked well for replying to 9trouble mail from 9trouble rather
than from rsc.

One feature that would be easy to add is that if one of my aliases
is named explicitly as a destination, the from address should be
that one.  You could also have your own header that pipefrom
notices, obeys, and removes.

This should give you ideas, at least.
