5 directories.
Any leftovers from past failures should be removed manually,
there is no automatism to purge them.
One way to purge is:
stop amavisd, delete all temp directories, restart amavisd
> Should the 8,000 directories be a concern?
It's not too bad by itself. But eventually this should be
cleaned. If new directories are accumulating, the cause should
be examined. It should stand out in the logs.
> What other reasons are there for these directories being abandoned?
Crashing processes? These disappear without a trace in the log.
Running amavisd-nanny manually every once in a while (or SNMP monitoring)
should be able to detect and report if there were any crashes since
the previous invocation of amavisd-nanny.

Yes, but only the ones still under control of sane amavisd processes.
Any uncontrolled leftovers are abandoned by amavisd.

Correct. As long as creating a file in such directory does not take
excessively long time, amavisd does not care how many files there are
in a quarantine directory.
