Do you have a project created for this software? Distribute it? I have a spam problem @ work. Looking into solutions. I looked at maps rbl http://mail-abuse.org/rbl/ not sure on using it in a production environment though (where the most spam goes to)
No, since it's mainly SpamAssassin with a little bit of procmail frosting and a small perl script on top. I was planning to just make it all available with the perpetually unfinished article I'm working on. (It doesn't help that there were 2.5 new versions of SA released since I started writing it ... <grrrr> ;) )
My main worry is someone sending e-mail to sales@company.com and it gettting rejected, and comany.com loses a sale. Is this an issue?
Well, that's the difference between a filter like SpamAssassin and a blacklist like the RBL. Personally, I use several blacklists for open-relays at the SMTP level, since it's unusual to have a false-positive from an open-relay test (depending on the test of course). For a company, I would use a filter (like SA) and just let it mark up likely spam. You can then leave it up to the users to decide what they want to do with it. (SA adds headers indicating how likely a message is to be spam (the score/number of hits), and what tests matched a given message.) Anything else that makes it through to delivery goes through SpamAssassin. Spams gets sorted into a seperate mail folder, and I then go through it and report the spammers, etc. There's some information about what I do for general filtering at: http://www.kluge.net/mailfiltering/ -- Randomly Generated Tagline: "And that's the success of Windows-it's mediocre, but it's easy." - Linus Torvalds
