I know many you here have your Discourse mail being sent via Mandrill
Are any of you seeing
@aol.com addresses bouncing mail more frequently?
Obviously you will only get the bounce email notification if you have configured an email address to receive these bounce emails under
Forward Bounce Notifications To This Address. But you can see both soft, hard bounces and rejected in your Mandrill outbound activity page.
AOL will not accept delivery of this message.
After talking to one user (a forum moderator) he found that Discourse emails were indeed ending up in SPAM - after asking him to flag them as “NOT SPAM” and removing his email address from the Rejection Blacklist emails were accepted again…
So far this has happened for 4 separate
@aol.com accounts - and just got me wondering if anybody else had seen the same?
The email notifications sent to these addresses would have derived from absolutely clean non-spammy posts containing interesting English content (at least to a human).
