Links which should look like:

[[message://2.11f23692084eb783e40c@NY-WEB01][Private beta invitation for Emacs Q&A site - Area 51 - Stack Exchange]]

are currently mangled into:

[[essage://2.11f23692084eb783e40c@NY-WEB01][Private beta invitation for Emacs Q&A site - Area 51 - Stack Exchang]]

This tiny patch fixes this issue.

Tested on OS X 10.9.
