A 90-Second Solution To Spam?
I'm told that the number 220 refers to the way a server responds to the "Hello" from an email client. The email client should wait up to 5 minutes to receive this 220 response. My spouse found a great bit of information from John DuBois over at The Armory. John has been testing the limits of impatient spamware, and has apparently figured out how to delay the 220 response for 90 seconds so that most rapid spam senders just give up and go away. He cut the number of spam server connections by a tremendous amount.
