Given what happened, I have yet another theory: My ISP (Speakeasy)
uses a method they call "graylisting" to cut down on spam. When they
receive an e-mail from an unknown or untrusted server, they send back
the WAIT(RandomNumberOfSeconds) command. Any real mail server knows
what to do with that, and they do. SpamBot2000 running on infected
Windows XP boxen (but I repeat myself!) don't, and the mail is dropped
on the floor. You may have just encountered the RandomNumberOfSeconds
here. When testing locally, I send to my MobileMe account, which seems
to process all mail nearly instantaneously. My Speakeasy account and
my Gmail account (which forwards into it) have the delay effect, so I
never can tell if my mailer is working.
