[TYPO3-english] sr_feuser with useEmailAsUsername = 1 not sending confirmation emails

[ktt]

Hello,

I set
useEmailAsUsername = 1
and 
enableEmailConfirmation = 1
but user doesn't get emails for 
confirmation after registration.
Maybe useEmailAsUsername = 1 doesn't work with
confirmation mode?

Thank you in advance,
Kast A.
