Bad news. I was not able to reproduce the problem on a VM, using
backups from the day the problem first occured. And worse, this night,
while I slept a troubled, disturbed sleep, dreaming of SMTP dialogues,
the list roster changed (one new member)- and the problem is gone.

I've been doing system administration tasks since 1997, and this still
feels more like voodoo than science, sometimes.
