Hi All, We are public email provider with postfix at backend. We are facing issue with getting black listed again and again. Currently we have setup reverse lookup, DKIIM and SPF to avoid getting listed into rbl's and dnsbl.
In most cases the issue arises because your servers are used to send spam. Fix this and you will not get blacklisted by any reasonable RBLs. If you don't fix it you will get listed again and again because this is how RBLs are supposed to work.
