Splitting up mailing list messages

[Pete Axon]

Hi,

I'd like to hear people's thoughts on what splitting methods people
use for mailing lists they are subscribed to.

Currently I have one group (mail.lists) where any subscribed groups
go, however the mails from all lists get all mixed up and the regexp
for the nnmail-split-methods rule is getting rather long.

Do people create a new group for each list with a corresponding
nnmail-split-method? How do you handle this stuff?

Thanks
Pete
