Hello everyone,
We also know of how those spam mailers work... register and pay for a new domain... sending lots of spam mails... requesting for refund... loop it... The frequent change of domain name makes blacklisting almost non-workable.
I'm thinking of adding a rule to existing mail server plugin that unless the "email address" is in the "whitelist", if the domain is registered within a month, it'll be discarded. Is there anyway to get this information programmably? I'm thinking about getting it from DNS records (I thought it could be in SOA) but it doesn't seems to be there.
Hope someone can give me a pointer to this.
Regards,
Lau Lei Cheong
