In my opinion, both.

I used to look after a system using Majordomo on a relatively small
FreeBSD system (P120, 16MB). Majordomo can somewhat process happy - and
if it runs in to the process limit while attempting to claim a lock
file evil things happen to the alias list. I ruined several list by
mailing 32 separate subscription approvals to Majordomo from my dialup
machine. When I connected they they arrived in quick succession on the
server, and the machine and majordomo went nuts, with sendmail and perl
processes everywhere. When the dust settled I discovered that the alias
file was empty. After restoring from a backup and perusing log files for
later subscriptions, I circumvented the problem by setting sendmail to
queued delivery only, with a queue run every 5 minutes. Not ideal, but
the machine carries a light mail load. It is arguable that I should have
tuned it better.

A majordomo list I subscribe to recently lost all its subscribers, I
assume due to a similar event.
