In the GAE/J documentation at "Google App Engine | Java | Services | Mail | (Mail Java API) Overview | Receiving Mail" with URL
http://code.google.com/intl/en/appengine/docs/java/mail/overview.html#Receiving_Mail it states "Your app can receive email at addresses of the following form: '[email protected]'" I want my app to send E-mails with the sender address of this form, but I have discovered the hard way that this form of sender E-mail address must(?) be fully in lower case after the "@". Trying to send from "administrat...@[myappid].appspotmail.com" fails with the exception "javax.mail.SendFailedException: Send failure (javax.mail.MessagingException: Illegal Arguments (java.lang.IllegalArgumentException: Unauthorized Sender: Unauthorized sender))" whilst sending from "administrat...@[myappid].appspotmail.com" is permitted by GAE/J. Jason's post in "unable to send email, got javax.mail.SendFailedException" dated 13 July 2009 with URL http://groups.google.com/group/google-appengine-java/browse_thread/thread/102d9e3012380b08/dc17a9b529a71c69?lnk=gst&q=SendFailedException&fwc=1 mentions this case sensitivity. In the interests of continuous improvement, please could the documentation be amended to point out the case sensitivity requirements of (the various components of) sender addresses? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
