Thank you for your reply,
The ISP is Broadviewnet.net, and what I am wondering is; why can I receive and not sent. Also I just went in to their domain website, and tried to use my account thru them directly. The e-mail that I sent went thru, so my question remains. By the way here are the smtp setup:
smtp-auth.broadviewnet.net.
Thank you again,
Salomon
