It provides a way to allow legitimate users to relay mail through an +SMTP server, while still preventing others from using it as a spam relay. +User's IP addresses are added to the map immediately after they have +authenticated to the POP or IMAP server. By default, map entries expire after +30 minutes, but can be renewed by additional authentication. Periodically +checking mail on a POP server is sufficient to do this. The POP and SMTP +servers can be on different hosts. |
