(>2 GiB) mbox's (fwd)

The report is correct. The c-client library makes no attempt to use the
64bit system calls; and thus flat files are limited to 2GB.
The recommended solution for mailboxes with aggregate size greater than
2GB is to use mix format instead of a flat file format. Even if c-client
were updated to use the 64bit system calls, flat files (especially in
traditional UNIX format) do not perform well at multi-GB sizes.
If there is some compelling reason offered, I will consider 64bit support.
However, as of right now, I am highly skeptical that the benefit would be
worth the effort, especially since there is a superior solution for large
mailboxes available now ("superior" since it will always work better than
a large flat file).
