Since update to go xaps-daemon push not working about dovecot-xaps-daemon HOT 2 CLOSED

It looks like your device hasn't registered for push notifications with your server.

If it has registered the log output would be like this:

2015/09/07 13:00:34 [DEBUG] Accepted a connection
2015/09/07 13:00:34 [DEBUG] Received request: NOTIFY dovecot-username="[email protected]" dovecot-mailbox="INBOX"
2015/09/07 13:00:34 [DEBUG] Sending notification to XXXXXXXX-YYYY-1234-ABCD-1234567890AB / ABCDEF012345567890ABCDEF1234567098ABCDEF12345677
2015/09/07 13:00:34 [DEBUG] Returning success:

So the "Returning success:" Line is normal (but it also did confuse me in the beginning).

So I guess the problem is, that you exchanged the software including the database but the devices don't know this. I think you could also trigger this by turning off and on the Push mode for this account on your device. If your got multiple users my advice would be to wait some time until the devices register themselfs again (I see this every few hours). It should look something like this:

2015/09/06 23:14:57 [DEBUG] Accepted a connection
2015/09/06 23:14:57 [DEBUG] Received request: REGISTER aps-account-id="XXXXXXXX-XXXX-1234-XXXXXXXXXXX"    aps-device-token="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"      aps-subtopic="com.apple.mobilemail"     dovecot-username="[email protected]"     dovecot-mailboxes=("INBOX","Sent Messages")
2015/09/06 23:14:57 [DEBUG] Returning success: com.apple.mail.XServer.4d4a1983-c679-466b-8f28-30a657ddc00c

You are right. I seems there is no device registered for this account. But the reason is something else. I think I see what the problem is: The database json format is between twistd-version and go-version is not compatible. So rewriting json file or re-register all devices should fix this issue.
