You can do it with the delay command in an ACL:

  delay       = 20s


will delay for 20 seconds.

I delay if certain things fail such as a reverse DNS lookup or if the
HELO name cannot be verified. It can be pretty effective. I'll share my
recipies if you like but I got most of the ideas from:

It's a very helpful document. :)
