	I would suggest making this flag visible on certain OSes.  For 
example, turned off by default but visible on Linux, and not even 
visible (without hacking) on OSes that don't need it.

	I know it kills performance, but this feature is needed for a 
reason, and RFC 1123 and 2821 make it clear that we can't lose mail 
just because we've had a system crash or some other known foreseeable
