Re: SMTP filter exclusions not working when return-path is empty

[Elton <ehd@xxxxxxxxxxx>]

If you setup your RBL filter for spamhaus as outlined the others day, 
the RBL Filter should exclude them; ie:

Filter : Spamhaus_Filter
Discard: X  Copy: X
Mail Addr: spamhaus@xxxxxxxxxxxxxxx

Dyn.Host   sbl.spamhaus.org   AND
Src.Addr   *domain1.com       NOT AND
Src.Addr   *domain2.com       NOT AND
Src.Addr   *domain3.com       NOT

Your SA filter should be:

Filter:  SpamAssassin_Filter
Discard: X  Copy: X
Mail Addr: spam_assassin@xxxxxxxxxxxxxxx

Dyn.Host   sbl.spamhaus.org    NOT AND
Src.Addr   *domain1.com        NOT AND
Src.Addr   *domain2.com        NOT AND
Src.Addr   *domain3.com        NOT

Body
----
Plugin Name  spam_assassin
