This could be caused by the AddTrust root expiration.

Holy jeez, I just found out this is also responsible for email newsletters failing this weekend. I’ll turn off https-only SSL for now and will re-enable once i get the certificate chain fixed.

Thanks for letting me know! Maybe this will spur me to switch to letsencrypt’s wildcard subdomain feature which is now shipping.

Good news, this is now fixed! It looks like there was a major news story on the invalidating of a root certificate on Saturday. I just updated the certificates and now newsletters are coming in again. I also checked and newsletters that weren’t delivered over the weekend should filter in over the next 24 hours.
