Detection rate of msbl.org

[James Brown <jl...@bordo.com.au>]

I’m thinking about using the EBL from msbl.org with SA.

Can anyone tell me what detection rate they are getting with it? Is it worth using, or would the spam be trapped by other methods (RBL, etc) anyway?

Pretty hard to find much information about how useful it is.

Thanks,

James.

I don't know what this is, but I guess it's not a purely SA based milter
as it gives a single reason for rejection.

Most of the hits on EBL that I get with SA are from addresses parsed out
of the body - often from HTML. If your milter can't do that you wont get
good results.

EBL is most effective against a subset of difficult spam where other
types of list don't work. It should really be judged on how it effects
what would otherwise would get past content filtering, not on what it
prevents reaching content filtering.

Not much yet, I got this one[1]. But I am having this check as one of 
the last. Most connections are already failing with 'Possibly forged 
hostname'

sendmail m4 macro for ebl

[Marc Roos <M....@f1-outsourcing.eu>]

 
I am also thinking about using it, and maybe creating my own ebl 
whitelist. Asked on the old fashioned sendmail newsgroup (cannot even 
search it), but they expect me learn this m4 language. I assume in this 
era I am not the first trying to use this, anyone like to share these 
few lines?
