I have my e-mail remotely on a GroupWise IMAP server. It seems like that server does not support annotations, and I always obtain some warning message about a failed SET ANNOTATION command after changing folder properties. It would be great if the IMAP resource could somehow remember what the server does not support, and at least not warn again and again...
We need to look at how to test if server support feature
The IMAP resource has a new maintainer, reassigning to him.
Fixed in 325443 (4.11.3)
