Sympa adds List-unsubscribe headers to messages (you can set this up
with "rfc2369_header_fields" parameter) ; though they're not widely
implemented in MUAs, it provides the subscriber with the unsubscribing
method (we recommend providing a <list>-unsubscribe alias).

For users who forgot their subscription address, we send subscription
reminders (REMIND command). Note that remind.tpl could be a complete
message.

Sympa does not allow recepient email inclusion in distributed messages
because it would break the grouping factor during distribution process.
This makes Sympa much faster than most MLMs.
