Maybe this is a little out of topic, but maybe some of you have experience with this.... What do you thing about chaining SPAM filters?, can this led to false positives faster?.
Example:
Internet ---> GW-Relay+Antispam (host1) ---> Antispam Appliance (host2) ---> MDA+Antispam (host3)
Regards,
If all antispam engines have a low false positive rate it wouldn't be a problem and it is not dissimilar to what happens with this mailing list and I suspect all mail in general. For example: My posts are spam scanned outbound by my workstation (1), then sent via gmail (which is a pretty good anti-spam all by itself) (2) then to the list server, where it is run thru Amavisd-New (3), and shotgunned out to the list, where each recipient has yet another one or two layers of anti-spam and malware detection, (4, 5, 6?). Multiple scans are the norm these days I suspect. Even Spamassassin runs mail thru several engines. I really don't worry about false positives much. People who were going to give me a million dollars via email will always ask if I got their email should their offer fall into my spam folder. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
