Hi All, One of groups.io's servers was listed by Spamhaus starting Saturday afternoon (https://www.spamhaus.org/sbl/query/SBL638016). I've been trying to contact them ever since, but they've been silent. I am humbly asking for help.
We're an email groups service, like Google Groups. Based on evidence provided by Spamhaus, it appears that some groups that migrated from Yahoo Groups when Y! Groups shut down contained some Spamhaus spamtrap addresses. On Spamhaus' suggestion, I built a reverification system late last year and tested it on a small group of users. Yesterday, I kicked off a reverification to a much larger segment of users. I then told Linode, our hosting provider, about it, and asked them to contact Spamhaus, as directed by their SBL listing. Linode did that, but has not heard back. I also tried contacting Spamhaus this morning, but haven't heard back yet. I am wondering what else I need to do. Thanks, Mark
