Interesting. I don't think that tpop3d needs to interact
at all with the soft quotas since the only operation in
POP3 which alters the size of the mailbox is DELE.

I'm not certain that making the contents of every folder
in a maildir++ is sensible, since it may break user
expectations about how folders behave (the `principle of
least surprise'). But it's a possibility.

OK, that's a good idea. I'll add that to the TODO list....

Errm. What's wrong with the log entries in syslog?

I shan't have much time to do any of this until early next
year in any case.
