I reported this as a bug (http://code.google.com/p/googleappengine/issues/detail?id=8246) but I'm starting to wonder if I'm just doing something wrong.

My app sends activation emails which usually show up immediately, except on Hotmail where they never arrive. Not in the spam folder, not anywhere. My "from" address is a Google Apps account. My app engine logs don't show any errors, and I don't see any bounces in the from account's inbox - but would they even show up there? Not sure how to even start debugging this one. I see some people complaining about the same thing in 2008 and 2010 but there were no resolutions. I first noticed the issue 3 days ago but it may have always been happening. Is anyone else able to send emails to Hotmail?

Possibly related - Yahoo accepts my app's emails just fine, but Gmail warns that the sender may not be who they say they are and add a big scary "via xxxxxxxxxxxxxxxx.apphosting.bounces.google.com" beside the sender. I would have thought since Google controls App Engine (which sent the email), Apps (which hosts the from account) and Gmail (which received the email) that it would know damn well the sender was legit. Am I doing something wrong?

Ooh, thank you very much, I'll give DKIM a try.

I also discovered SPF records and set that up:

Now instead of being rejected outright, my emails are going to Hotmail junk folders. A step in the right direction!
