[IMC-Tech] File 13 for Email, I Give Up

[Joe Futrelle]

Mailman's issue with its crappy admin interface is longstanding and I  
don't think we can wait for it to be fixed. That said, I'm as unclear  
as Stuart about how to interpose an open-source spam filter between  
incoming mail and whatever's running the distro lists--Mailman or its  
eventual replacement. Rolling our own spam filter with heuristics  
will only buy us time.
