Hi Tom,
Saw you had your problem fixed over our support email, but figured I'd post some tips here for others who might see it:
* For the Login user ID, use your full email address (i.e.
[email protected]).
* Leave your password as your password.
* try the following combinations (one at a time if the first one doesn't work) for SMTP port number/ security :
587, TLS
465, SSL
25, SSL
587, TLS is what ultimately worked in this case.
