[Mailman-Users] Accepting "implicit destination" messages based on other headers?

[Ivan Fetch]

Hello,

    I'm wondering whether it is currently possible, or whether there is 
something on the drawing board, to allow accepting of messages normally 
held for "implicit destination" based on other headers than To or CC?   We 
would like to accept certain messages based on another header, without 
opening things up to much by putting something overly general in 
acceptable_aliases.


Thank you,
Ivan Fetch.
