[imp] Maximum # of messages?

I can think of two things: either the mailbox is corrupted, or the size of the 
mailbox bumps up the amount of information that we need to store in the phplib 
session so much that phplib dies and gives us bad information. In that case, 
either decreasing the amount of messages we keep track of at once (you can find 
this at the top of the messageRange() function in mailbox.php3 and 
message.php3), or increasing the session data field size in Oracle, might help.
