RFC Errata
RFC 5465, "The IMAP NOTIFY Extension", February 2009
Source of RFC: lemonade (app)
Errata ID: 4833

Section 5.2, 7 says:
Section 5.2 paragraph 4: ... The FETCH response(s) MUST follow any ESEARCH ADDTO responses. Section 7 paragraph 2: Note that the EXISTS response MUST precede any FETCH responses, and together they MUST precede the ESEARCH response.
Notes:
As the RFC is internally inconsistent on this point, servers can have either behavior. I know of at least one deployed implementation that follows the MUST in section 7 rather than the one in section 5.2.
At this point I can't suggest specific corrected text, so this is a hold-for-document-update issue.
