[Mailman-Users] Umbrealla list member verification

[Mark Paxton]

Hi,

I'm after some advice about the set up of my mailing lists... any help 
would be appreciated!

I have an number of umbrella lists that sends to a combination of 3 
subscriber lists.  e.g. U1 sends to S1, S2 and S3, but U2 sends to S1 
and S2 only.

I'd like it so that any member of a subscriber list can send to an 
umbrella list... but I'm hot sure how to do that.  I think the easiest 
way would be to set up the sender filter so that it allows members of 
another list, though I don't know if that's possible.

Any suggestions would be great!

Thanks,
Mark
