[Alpine-info] Bug#478545: [alpine] alpine does not support large (>2 GiB) mbox's (fwd)

[Mark Crispin]

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).
