Hi All, Some apps have experienced delivery problems with mail recently. This was manifested as mail being sent from the app, and quota charged, but the mail not arriving at the destination (not even in the spam folder).
As you can imagine, any large service that lets applications send bulk email is something of a honeypot for spammers. We’re working constantly to balance delivering good mail from good apps against preventing spam. In response to an influx of spammy apps, we changed our outbound spam filtering to be more restrictive which, unfortunately, raised our false positive rate. We’ve modified this change and made some others so existing apps should be back to previous levels of email deliverability. DKIM support is in 1.6.3, which will improve spam evaluation considerably, and there are some good hints here about preventing your legitimate messages from being marked as spam: http://support.google.com/mail/bin/answer.py?hl=en&answer=81126. We’re planning on adding some sort of feedback mechanism so your app will know when its mail is being rejected, rather than just silently failing. There is no definite release date planned for this. If you are still having problems with mail deliverability, or you have other questions, please contact us at http://goo.gl/ldsGA Thanks- -Moishe Lettvin Mail API Tech Lead -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
