Quoting Chris Lightfoot ([EMAIL PROTECTED]): > Are people seeing a lot of SRS in the wild? A quick census > of my mail suggests <0.1% SRS for both real mail and spam.
I implemented it after my domain was abused in a joejob once. I got lots of bounces for messages i really didn't send. Mine look like this: [EMAIL PROTECTED] SRS0 being just a 'tag'. The hash is built by combining a secret key with some characteristics of the email. The 362 is a date-stamp by which this 'token' can be dated, and the original address follows after it. I once had 'mxhost-timestamp' prefixed on the domain-part (dot-135301.srs.freshdot.net), but that broke many greylisting setups. I'm still very happy with the extra layer of 'noise protection'. It still catches ~10 bounces a day :) Only had some minor problems with flakey mailinglists and funky callout setups for which i have made certain 'whitelists'. Thing is, you can only implement it on a domain you have absolute full control over the incoming and outgoing mailservers. Or else it's useless / will break very hard.
