This bug has occurred because I never considered the possibility of
delivering into anything other than the new folder; I hadn't thought of
direct delivery into subfolders. (I'm very unimaginative at times.) Exim
was using the maildir_quota_directory_regex to exclude .Trash only when
it was adding up the size of a mailbox. It was not using it when doing a
delivery. Thus, the size of a new message was always added to the
maildirsize file.

I have modified Exim so that it checks whether a delivery is into a
directory that matches maildir_quota_directory_regex. If not, the
delivery is exempted from all quota calculations. I hope this will fix
the problem.

The code has been committed to the CVS and should therefore be in
tonight's snapshot, as well as ultimately in the next Exim release.
