[Evolution] Evolution - Dealing with groups

[Ubuntu Shoto Dojo <ubuntu shotodojo com>]

I can send to a group as a Contact List.

How can I receive from a group?  I need to receive response (or unexpected 
messages from the group and put them together (group them) in a folder.  I 
can find nothing in the filters which seem to have any such ability, maybe
[Sender] [is in group] [specific Contact List]

This is non-trivial (and perhaps a killer to use Evolution), as I currently 
have 17 folders into which I need to sort incoming emails, based on 50+ 
contact lists, ranging from 6 entries to 250+ entries in the list.  Trying 
to manually maintain individual email addresses in filters as things change 
is a complete no-go.

I find, in the Help -> Sorting and organizing mail -> Using Filters -> 
Available Filter conditions references to:  
Expression - "the Scheme language used to define filters" but the link 
merely goes back to Using Filters, and searching the web for for 
<Linux "Evolution" filter "Scheme"> got me nothing.
Free From Expression - a special syntax, but the link goes to an ancient 
bug report and some crude documentation which only provides for a more 
complex search syntax/semantics.


Is there some way to compare an incoming email address to a Contact List?
Is there any documentation for the mentioned Scheme language?

Is there any documentation for the storage format for
1)  Contacts and Contact Lists
2)  Filters
because I could write (bash/awk/perl/whatever) scripts to update the 
filters based on the lists, if that is all that is available.
