How well does accessing mysql scale to high volumes? And I assume the 4 MXs will be querying across tcp/ip to a shared db sever? The question is not whether you can do it, but whether you should do it. Entertaining yourself with technical prowess and trickery really should not risk obstructing mail delivery when the trickery fails. Keep all critical execution and data paths as short and as simple as possible. Len
