The mailing list for listmasters using Sympa

[Scott Balmos <address@concealed>]

Two questions...

I know the Mailman software has this problem, and was wondering if Sympa 
does also. Assume a user is a member of lists A and B, and that a list C 
is created which includes lists A & B (using include_list in the list 
config file I guess). When a person posts to list C, since our example 
user is a member of both included lists, will that person receive 
duplicate copies of the post (one going to list A's members & another to 
list B's)?

Next... Does Sympa handle, at all, list members who have extended 
addresses (e.g. user+foo@bar)? Again, this is another problem that 
Mailman has. Delivering from Sympa to the user's mailbox is no problem, 
obviously. But when that user posts to a private (subscriber-only) list, 
they most likely have their mail client set up to be user@bar, not 
user+foo@bar. Will Sympa recognize this is still the same person, and 
allow the mail to go through? If not, where abouts in the code is 
address recognition handled, so I can possibly add this in as a hack of 
some sort?

Thanks!
