Sorry for not providing the full info at the beginning. I looked before mailing at the code and found it used off_t, which is 32 bit on my systems. Below are 2 setups in production; both of them have 32-bit off_t: SLES 9 / courier-imap 4.0.6 / vpopmail delivery SLES 8 / courier-imap 4.0.6 / custom delivery > > 1. The limit for a mailbox is 2 GB.

It makes it very difficult for courier-imap (or any other program > in fact) to support quotas over 2GB in a portable way.

I was wondering if you plan to add support for non 64-bit off_t systems. To implement maildir quota in a sane way, I plan on writing a shared library for maildir quota support. > > 2.
