I've tried this ... I revoke the certificate on the APNS portal ... and it is now gone.
The portal will not let me create a certificate there, it says it has to be through the server app.
In the server app, I've disabled and re-enabled the push notification, and still get the -1200 error. I also have tried creating a new Apple ID and creating a new certificate under the new ID and get the same -1200 error
<SIGH>
I know everyone says, just upgrade, but this will take multiple hours, since I have multiple domains hosting, forwarding, mailman servers ( which in itself took months to get working right ) customized spamassassin settings ... basically the server has become useless now. If I'm going to spend hours restarting, it certainly won't be with OSX again ... it was an uphill battle to get it working originally well, probably will move to a hosted solution and not fight the battle anymore.
It would have been nice if we had some type of warning ... Apple certainly could have pushed out an email from the APNS portal just like the renewal notice ( which doesn't work for most of the servers that I can tell ) and suggested a solution ... I've learned that Apple is just not serious about enterprise solutions ... or concerned about their implementations and how this affects other people that have put trust into their solutions.
