http://www.critsend.com/ SMTP settings for e-Newsletter

Hi,
I have signed up with http://www.critsend.com/ for SMTP relay and trying to include SMTP settings.
(http://www.critsend.com/smtp-service-setup/)
However, receiving cannot authenticate with following setting ssl://smtp.critsend.com:465
and
Could not connect ssl://smtp.critsend.com:25 or ssl://smtp.critsend.com:587

Setting ssl://smtp.critsend.com and port 465 is works with other newsletter client perfectly.

Kindly help me to solve the problem ASAP.
