Interesting! - I am not an rmail user, and for whatever historical
reason rmail support of BBDB has been minimal so far.  But it seems
that auto-generating rmail-output-file-alist is a "typical" task for
BBDB.  What would be useful here?

The docstring of rmail-output-file-alist says that it is a list of
elements of the form (REGEXP . NAME-EXP).  So BBDB records could
have a field rmail-folder that hold a string NAME-EXP.  And REGEXP
is derived from the mail addresses in a record?

bbdb/vm-auto-folder does something similar for VM.
