HRD Migration and issue with e-mails sent using the old app name

[PK]

I just migrated my main app to HRD using the tool introduced with 1.5.5. All in all a very good and fast experience, except one issue.

My old app name was foo, the new name is foo2  (fake names for the sake of the example). After the migration as expected:

1) requests to foo.appspot.com get redirected to foo2   GOOD

2) e-mails to foo.appspotmail.com get redirected to the foo2 handler   GOOD

However, I was surprised to find out that e-mails attempting to leave foo2 with an xxxx @ foo.appspotmail.com from address get rejected. This forces me to reveal to my users the new app id and I need to ask them to add this domain to their antispam filters.

Is this something that could be fixed? Should I open a case?

Thanks,

Could somebody from Google be kind enough to reply to this?

This remains an annoying issue for my users. I filed issue http://code.google.com/p/googleappengine/issues/detail?id=6243 to track it.

Thanks,
