Sounds like letting it through because it's SPF-compliant is not such a 
good idea. Why am I not surprised? That's probably configurable (I use 
postgrey, so I'm not sure).

OTOH, maybe she is a nice girl and you might like her pictures of ligers 
and ninjas.

Also I recommend setting your timeout to something like 30 seconds. The 
one disadvantage of greylisting is that when you sign up for a new 
account on a website you have to wait for that email to come through. 
Sometimes they have a button to resend the activation email, which will 
come through after the timeout. It stinks to have to wait 5 minutes to 
hit that button, but 30 seconds is almost up by the time you checked 
your email, saw it wasn't there, and remembered you have greylisting.
