I suspect very few can, if any. The imtest tool which comes with Cyrus supports this feature. I thought the perl module Mail::IMAPClient supported it, but it appears you would have to tie it to imtest (which is given as an example in the source distribution of Mail::IMAPClient). In the context of the original question, I'm not sure it is even necessary to authorize as the end user. An admin user can open any mailbox on the system to find the notification messages and delete them. If you want to simply read a user's mailbox (not *be* the user), then an admin can grant access to the mailbox to any other Cyrus user. We do that here to help diagnose user problems.
