There are a bunch of LISTSERV-related documents in the DOCUMENT
filelist at UCF1VM (aka ucf1vm.cc.ucf.edu) These have probably been
abstracted from various LSTxxx-L discussions but comprise some
distilled wisdom.
 
References to things that *I* didn't know about:
 
SUPPORT database
Semi-Moderated lists
BITEARN database TECH report
 
I don't know if these all survived into modern day usage (well TECH did)?
