We have had some reports of incoming email from AOL users being bounced back to the senders. After some extensive research over the last few days we believe we have managed to address this problem, adjusting the configuration of one of our anti-spam measures (greylisting) to allow for the fact that AOL’s handling of outbound email doesn’t play well with greylisting.
If you are a NinerNet client and have any reports from correspondents with AOL email addresses indicating that email from them to you has been returned as undeliverable, please contact support.
Update 2010-06-15 07:28 UTC: Apparently this issue has not yet been resolved. We contacted AOL yesterday to find out why some of their mail servers are bouncing email prematurely and without reason, but their auto-response says it could take seven days or more for them to respond, it at all. We will post updates as they become available.
