multiple messages to one address in multiple lists?

[Kyala Shea <amiga @ northcoast . com>]

I'm a new majordomo user and am wondering if it checks for repeat
addresses in a message sent to multiple lists.  In other words, if a
user is subscribed to multiple mailing lists and an e-mail is sent to
more than one of those lists, will the user receive multiple copies of
the message?  Is there a way to prevent the user from receiving multiple
copies in this case?

Thanks much,
Kyala
