 Because of this it is often not worthwhile putting addresses onto the Blacklist manually either. The only case that is generally useful is if you have signed up to a mailing list, and they are refusing to remove you from the list, but this is quite rare. Because of this it is often not worthwhile putting addresses onto the Blacklist manually either.

-=====Local Addresses=====+====Fields which the Blacklist checks==== 
 +The Blacklist currently checks the addresses in the **Return-Path**, **Reply-To** and **From** header fields. 
 + 
 +The Blacklist will not be checked if the header contains three or more 'Reply-To' headers (this is an invalid message, and matches another spamfilter rule) 
 +=====Whitelist===== 
 +====Local Addresses====
 If you put an address on the whitelist which is also in a 'local domain', then, by default VPOP3 will ignore that when checking //incoming// mail. This is because spammers often send spam pretending to be from the same domain as the recipient. In most cases, mail from local domains will be sent locally, not incoming, so, usually, this is a sensible rule to follow. If you put an address on the whitelist which is also in a 'local domain', then, by default VPOP3 will ignore that when checking //incoming// mail.

 +
 +The 'Reply-To' address will not be checked if it is set to 'noreply@facebookmail.com', as that would whitelist a lot of spam, because that address is often added to the whitelist by out-of-office replies.
 +
 +====Whitelist result info====
 +The spam filter adds a header to the message called 'X-VPOP3-WL' which contains diagnostic information about the whitelist results. It may also add a line 'X-VPOP3-SpamWL' if the whitelist checks have been skipped for some reason.
