When you send mail via qmail it eventually goes through qmail-inject, which
respects these environment variables:
ENVIRONMENT VARIABLES
For the convenience of users who do not run qmail-inject
directly, qmail-inject takes many options through environ�
ment variables.
The user name in the From header field is set by
QMAILUSER, MAILUSER, USER, or LOGNAME, whichever comes
first.
The host name is normally set by the defaulthost control
but can be overridden with QMAILHOST or MAILHOST.
The personal name is QMAILNAME, MAILNAME, or NAME.
The default envelope sender address is the same as the
default From address, but it can be overridden with QMAIL�
SUSER and QMAILSHOST. It may also be modified by the r
and m letters described below. Bounces will be sent to
this address.
If QMAILMFTFILE is set, qmail-inject reads a list of mail�
ing list addresses, one per line, from that file. If
To+Cc includes one of those addresses (without regard to
case), qmail-inject adds a Mail-Followup-To field with all
the To+Cc addresses. qmail-inject does not add Mail-Fol�
lowup-To to a message that already has one.
The QMAILINJECT environment variable can contain any of
the following letters:
c Use address-comment style for the From field. Nor�
mally qmail-inject uses name-address style.
s Do not look at any incoming Return-Path field.
Normally, if Return-Path is supplied, it sets the
envelope sender address, overriding all environment
variables. Return-Path is deleted in any case.
f Delete any incoming From field. Normally, if From
is supplied, it overrides the usual From field cre�
ated by qmail-inject.
i Delete any incoming Message-ID field. Normally, if
Message-ID is supplied, it overrides the usual Mes�
sage-ID field created by qmail-inject.
r Use a per-recipient VERP. qmail-inject will append
each recipient address to the envelope sender of
the copy going to that recipient.
m Use a per-message VERP. qmail-inject will append
the current date and process ID to the envelope
sender.
So clearly it provides for overriding the name, but not for simply adding an
extension. I think adding this functionality to nmh would be useful.
I would then also be able to repackage my spam-proof addresses in a way that
I wouldn't be embarrassed to share with others.
