cdml mail bug in 5.5?

[walkingtoyou]

today i tested to upgrade my 5.0 unlimited to the
5.5 unlimited and all sites are ok. but only the cdml
mail function does not work. every test show me
the error -101. after this strange problem i change
back to version 5.0 unlimited and all the cdml mails
are working.

any ideas?
