Track invited emails

[Dwaynebailey]

Currently there is no tracking of people who have been
sent invite emails.

This cause a problem in that you might invite people
from a given list of emails to join the mailing list.
 Then from some other list or at some other time you
might issue another invite. Receiving a number of
invites from a list that you are not interested looks bad.

It would be great if Mailman could track email
addresses that have been invited and just like invites
are not sent to people already subscribed they are not
sent to people already invited. The use could of
course have the option to ignore the "already invited"
list.

This is more of a feature request. So moving this to RFE.
