For what it's worth, I've used Sympa as my go-to list manager. It's just 
a little more cumbersome to set up and administer - but a lot more 
functional than Mailman, particularly when running multiple lists.  Also 
FOSS, but with folks who are actually paid to maintain, update, and 
support it (out of INRIA, I believe - basically funded to support the 
French research community).  It had a work-around for DMARC within a few 
days (thanks Steve!) while it took quite a bit longer for a patch to 
show up for Mailman.

In theory, there is no difference between theory and practice.
