Can send email via gmail but wont send registration email? - Joomla! Forum - community, help and support

well have spent on 5 hours on today , have ti working point.

my settings follows

joomla 1.5.14

var $mailer = 'smtp';
var $mailfrom = 'admin@mydomain.com';
var $fromname = 'my site';
var $sendmail = '';
var $smtpauth = '1';
var $smtpsecure = 'ssl';
var $smtpport = '465';
var $smtpuser = 'admin@mydomain';
var $smtppass = 'mypassword';
var $smtphost = 'ssl://smtp.gmail.com:465'

i can send emails mass email section. works fine , sends them out registered users (right have manually enable them).

however cannot, life of me, send new emails user registration.
i keep getting "cannot connect smtp error".

i have tried pretty on forums. took me 5 hours send emails via mass email.
any ideas why mass emails work, new user registration doesnt?

thanks

again appears working correctly. still not sending new user registration emails.
