Spam prevention requires preventing open relaying through email
|
||
|
|
servers. However, legit users want to be able to relay. If legit users
|
||
|
|
always stayed in one spot, they'd be easy to describe to the
|
||
|
|
daemon. However, what with roving laptops, logins from home, etc.,
|
||
|
|
legit users refuse to stay in one spot.

|
|
pop-before-smtp watches the mail log, looking for successful pop/imap
|
||
|
|
logins, and posts the originating IP address into a database which can
|
||
|
|
be checked by the MTA, to allow relaying for people who have recently
|
||
|
|
downloaded their email.
