1.51 + a method of preventing e-mail spam;
1.52 + 1) utilizes standard behavior of legitimate e-mail servers that tries to redeliver the message multiple times when a temporary error occurs
1.53 + 2) expects that spammers are not going to redeliver in that case, because they are focused more on quantitiy than quality (few lost messages are not an issue for them);
1.54 + MTA equiped with a greylisting filter will respond with a simulated temporary error to incomming messages from an unknown sender;
1.55 + when the sender attempts to deliver the massage for the second time, the message will be accepted (if it is long enough after the first attempt);
1.56 + this method is stateful which means that the MTA server needs to maintain a list of senders and their send attempts – this list is called greylist;
1.57 + disadvantage of this method is that it causes delays in the e-mail delivery;
1.58 + this disadvantage can be partially mitigated using a whitelist: trusted senders (domains or IP addresses) are put on the whitelist and do not have to wait even if they are sending the first message
