So this is 5 GB. I don't know how exactly the limits work with 32 bit
systems, but if you get the error with >1 GB files then my guess is that
this 5 GB gets wrapped to 1 GB (5 mod 4 = 1).

Kernel gives this error when it reaches the maximum file size limit.

If you don't want a limit, just set mailbox_size_limit = 0.
