[Mailman-Users] Export messages to another archiver

[Vincent Le Goff]

Hi everyone,

I'd like to find a way to export my list's messages to use a different archiver.

Is it possible to export messages with the 'withlist' command?  I
didn't find how to retrieve the list's messages.

Or is there some hook system or something to execute a specific
command when a message is received (I tried to find a postfix-side
configuration, but it doesn't seem to be possible).

Thanks for your help,

Vincent
