[Mailman-Users] From vs Sender

[Michael Stoic]

Hello,

I am testing a web page Mail-In form that emails the form contents,
including a user supplied email "From" field, to a Mailing List. The ML in
turn distributes the entry to the subscribed members.

In setting up the Mailing List, I'd like to restrict the allowed posters to
be only the "system" - which ends up, SFAICT, being either
nobody at sh2.1-sh.com or mailman at sh2.1-sh.com  In other words, I'd like to
make the ML posing privileges available ONLY to the web page/ OS/ Mailto
Script - whatever is the correct term here - that originates the ML bound
message.

The problem I am running into is that the above values end up in the
 "Sender" variable of the message header, here is an excerpt from the
header:  [ Sender: Nobody nobody at sh2.1-sh.com ], but Mailman 2.01 only wants
to check the "From" variable to perform the filtering.

Since the "From" is user supplied via the form, every time, and therefore
impossible to predict, I can only get the message delivered if the ML is
left open for anyone to post. If I tell Mailman to accept from either
nobody at sh2.1-sh.com or mailman at sh2.1-sh.com or both, he refuses to process
the message.

So the question is: is there a reasonable workaround? Can I get Mailman to
approve messages based on the "Sender" variable instead of the "From"
variable?


Many Thanks!
