I asked about something like this on the ezmlm list, because one of our list
admins was having problems with people being subscribed under addresses
different to the address they thought they were subscribed under. (Mostly
Windoze users that didn't read the confirmation message and/or deleted it).
This meant that the list admin had to manually remove users when they
complained of not being able to unsubscribe, usually to the mail list with a
few explecitives attached. Sometimes the admin had to make a guess at what
the subscriber's address was and hope that some innocent bystander didn't get
caught in the crossfire.
Perhaps this rewriting could be restricted to the last line of the message,
and then you could have something like:
To unsubscribe, send mail to:
[email protected]
with qmail-remote rewriting ?USER? and ?HOST?.
But that's not an optimal solution. Are there any characters that are not
allowed in SMTP messages? I thought about from my reading of Dan's web page
LF's can appear in the middle of a message.
