This is big, and that's an awful lot of sendmails... but the time on this
sucker is *incredible*!

Can you limit the number of sendmails, and see if that helps?  Use:

	-O ConnectionRateThrottle=10

You may want to seperate enqueueing from queue runs:

	-q10m

Maybe making it explitly delayed:

	-q10m -O DeliveryMode=q

You may also want to use:

	-O ForkEachJob

but I wouldn't really recommend it as a panacea...

These seem to have an especially huge number of mappings:
