From the developer:

MBOX Breaker is a Mac-only program that allows you to split mailbox (.MBOX) files into smaller files of any size you desire.

Apple Mail, for instance, has a 1 GB limit on the size of .mbox files it will let you import, so MBOX Breaker could split your existing mailbox into smaller files that can be successfully imported.
