This leads me to believe it's a problem with the network. Mail isn't
typically a big resource hog in the cases I've seen. SA can be,
although it seems to be quite fast on my setup. I guess I'm just lucky.

I'd think about moving SA off to a different dedicated machine, but
if there are network problems, this may serve to only slow things
down further.

More details would be helpful. Then someone with real knowledge can
chime in and help instead of me. =-)
