I guess this is a question I was wondering about (and didn't explicitly
state): is it reasonable to assume that a mailbox (or even that a whole
message) for a pop session will fit in RAM?

This is not designed as an industrial-strength APOP server that will meet
all needs, but I do have to be aware that it can break, especially since
it's running as root. :)

People have a way of sending snarky attachments (like PowerPoint docs)
that are huge.

I suppose I really answered my own questions (no and no) and I'll have to
work around them. :)

Ah, good point. I forgot about the -c option.
