Cannot transfer one organisation to another

[Gero]

Hello, I did some mess while setting up my Jira products, and have now 3 different organisations. Would like to get rid of two of them, but as far as I've understood it's incredibly impossible. So I tried transferring both to the only one I'd like to keep, but I keep receiving an error message saying like

The action cannot be performed at this time. Try later.

 Somebody can help me about that? I'm administrator of every organisation, and the only one with a verified domain is the target one.

Here attached an image of what I get; it's in Italian, but you can see the error message at the end.

Hello Ken, If you are able to send the email successfully then I suggest that you should ignore this error message. I checked it's source code also and it seems like it's due to backward compatibility with the mail library which Jira is using and there is still some workaround left from them to completely fix the issue and it's just a notification message left in log. But I have seen that all my emails are sent successfully.

I think there's something wrong with the example. I just sent a Gmail to myself and used that, and it worked fine.

I'm having this problem as well with the simple mail handler in the Atlassian example. Using JIRA 6.1 with SDK 5.0.4.

Any help?
