Nothing special.
What is the maximum amount of message allowed?
It's limited only by virtual memory on your system and your disk's
filesystem.
Is there a maximum total disk size? (So far, the mailbox only
takes about 300MB or about 7KB per message.)
On many UNIX systems, the limit is 2GB.
2) What is the algorithmical complexity of selecting and synchronizing a MBX
mailbox? On my machine, it appears to be roughly proportional to the time it
takes to 'cat' the mailbox, so I'd suspect its linear.
It is linear following the number of messages in the mailbox.
With traditional UNIX mailbox format, it is linear following the number of
bytes in the file.
2.5) Is there any possibility of a c-client compatible mailbox format for
which selecting, synchronizing, and other common operations are
constant-time?
I am developing such a format now.
