That was my favourite way of building a large mailbox for testing ;) A few 
appends, then a dozen or two copy commands.

More relevantly, trying to prevent one thing by blocking another is just 
whackamole. Tiresome and ultimately fruitless. Multiappend, copy, catenate 
and SMTP all offer ways to get around the size limit, if that's the game.

I sort of like 2088bis, but I think it should state what it tries to 
achieve and forget the rest. This could be good: "This is intended to limit 
the resource waste by errant clients, not to enforce any kind of quota 
(RAM, disk space, I/O or anything else) or to stop malevolent clients. 
Malevolent clients are considered a task for the system administrator."
