I suppose this would go back to the DNSBL. But unless there is one already, this is still a recto-active manner to do things as it will take time for the databases to build up. I am currently looking in all eagerness however. Perhaps starting one up wouldn't be such a bad idea as a mid to long term project. > I'd look at another route - like making the signup process have some > other identifier which is less likely to be throwaway, such as a credit > card verification or PIN-via-SMS to a specified phone number which you > can correlate multiple signups against.

We currently do SMS verification yes - whilst the costs aren't prohibitive, we are battling with SMS delivery, especially in the US. There was some laws past a few years ago in the US which makes it rather difficult for non US numbers to send SMSes into the country for spam reasons. SMS and Credit card's aren't 100% fail safe either just so BTW - there are a few places on the net where you can get a temporary number and receive a SMS via the web (similar to DEA emails). Credit card numbers can be generated too. -- Regards, Chris Knipe -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
