I'd like to send a newsletter for my customers. So i decided to try mailman with a read_only mailing list. But i'd like my customer to be able to choose between several mailing list about different subjects and send them a single mail once a day with the content of all the mailling list they had subscribed.

I hope this question hasn't been answered yet because i didn't seek to the end of the mailman-users archive.

Thanks by advance
