Registration Problems - no email received by user

I am not sure what I don't have set right but I can not register a new user
I get the following error:

Error (ERROR_UNKNOWN) :
in modules/core/classes/helpers/MailHelper_simple.class at line 90 (gallerystatus::error)
in modules/core/classes/GalleryCoreApi.class at line 2478 (mailhelper_simple::sendtemplatedemail)
in modules/register/classes/GalleryPendingUserHelper.class at line 232 (gallerycoreapi::sendtemplatedemail)
in modules/register/UserSelfRegistration.inc at line 170 (gallerypendinguserhelper::sendadminemail)
in main.php at line 182 (userselfregistrationcontroller::handlerequest)
in main.php at line 86
in main.php at line 77

I can send a test email but no e-mail is received by the user. There is a record in the PendingUser table and yes I have checked the users junk mail to see if it was routed there as I am the user I gave the same email addr I used in the Test Email (Which I received)

By the way where is the pop/smpt/imap data kept?

I would appreciate any help as we are anxious to get this implemented at our site.
