Re: How do you deal with spam?

I deal with it in a number of ways as I have yet to find one perfect solution. I do strict header and body checks, run it through RBLs, enforce RFC compliance, and only then does it go through Spam Assassin. That seems to take care of 90% of the problem. For my users that pull their mail off the server, their local anti-spam stuff gets the rest.

I have this C4I.org proprietary company comprised of members of the disbanded Canadian Airborne Regiment, and elements of the Special Boat Service. Lets just say we have developed a solution that effectively deals with not only the networks that send out spam, but the spammers themselves...

Layers of crap reduction..

I ended up going with the layered approach, and it works OK. I am sure there is a better approach, so if I left anything out, please mention it.

- First the router blocks 1918 addresses and all the BOGON addresses.
- Then it hits the black hole lists (Yes, there are two)
- Then the access list for sendmail lets mail in only for email accounts that actually exist.
- Then the mail server has some rules, like if the addresses doesn't reverse, etc. it gets dropped.
- Then the sidfilter checks SPF and Sender ID records (Don't forget to add SPF records for your domains!)
- Then (The only commercial piece here) the cloudmark spam filter kicks in
- Then the A/V scanner picks off any obvious dumb stuff
- Finally the mail gets delievered!

But wait, there is more...

Then Eudora Junk filtering picks off a few more. In the end a big vortex of crap gets reduces to a small stinking trickle.

Re: How do you deal with spam?

Gmail has a great spam filter. I think I've gotten one spam e-mail in my inbox in close to 3 years of using it.

I do, however, go into the spam folder and read it when I need a laugh.

I have one e-mail that's dedicated to spam


Other than that, I can tell it's spam by the header.

Re: How do you deal with spam?

My ISP (using spamassassin) blocks 90% of spam before it gets to my inbox.
I do a bit more with some custom procmail stuff before it hits my mutt anti-spam plugin.. oh wait, i don't have one.

Poetry spam anyone?
I do seem to get some very intresting spam that I almost don't mind... its like strange seemingly pointless words, sometimes poetic. (then there's some HTML in an attachment with a small picture of something spamlike)
