I have received the following request: "We request to be on your whitelist. We are double opt-in only.
We operate using several different upstream providers, and the complete list of our ip address blocks can be found at " Apparently they provide mailing-list services and our spamfilter has refused some of their mailing-list-related mail. As far as I understand spamassassin's whitelisting it does not work with "ip address blocks" but with the sender addresses or domains. If I would do what this person requested I can do it in exiscan by just not referring email coming from that IP range to spamassassin. That opens up a gateway for people who spoof thos IP addresses to bypass the spamfilter. Now my questions: How would administrators on this list would handle a request like this? Should I ask particulars on a mailing list basis to do the whitelisting?
