That's not entirely true.  There are plenty of mail servers that are not
"greylisting compatible".  Some sites will retry sending from different IP
addresses, others that run mailing lists will change the sender address for
bounce detection...  Those can cause issues with greylisting.

Though, yeah, in most cases greylisting works great with very little
training required.
