The following is based on thinking because I haven't actually
implemented this yet:
It should count everything in there because separate disk quota progs
can create a limit which exim would hit and this would generate errors
in the wrong places.
My thinking is that if exim detects that there won't be enough space for
the mail, it could cope by freezing or deferring delivery. If the
external quota program stops it half way through, I can see other
problems happening.
Here we have users' maildir sitting in their home directories, and we
have a quota limit on home directory sizes. At the moment, I don't have
exim doing quota checks at all because we just put lots of disk space in
so I have time to work out the details before I start hitting ceilings
(and in any case it's an older version of exim), but eventually I'll
want to turn on quotas in exim and they mustn't conflict with those on
the file server.
Just a few cents worth. :)
