One last thing - if this affects you, PLEASE star this issue: http://code.google.com/p/googleappengine/issues/detail?id=3161&q=DKIM&colspec=ID%20Type%20Component%20Status%20Stars%20Summary%20Language%20Priority%20Owner%20Log
And Googlers, this is a BIG deal for me - Yahoo Mail is used by Xtra, NZ's largest ISP. My application allows parents to book parent-teacher interviews online, and is very popular - it now caters for over 40% of NZ school students (and a growing number of Australian and US parents too) - over 300,000 people have used it. But a good proportion (30-40%) of those parents now don't get their booking confirmations because of this issue. I have staunched the flood of support calls by detecting Xtra email addresses and warning them they won't get their messages (and asking them to hassle Xtra/Yahoo on my behalf), but allowing DKIM headers would make delivery far more reliable. I also reckon DKIM is the answer to spam and salute Gooogle for implementing it for Google Apps - but PLEASE PLEASE PLEASE can we have it for appengine too! -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
