Hello,

I had same problem before and I resolved it by checking "ISP's SMTP Server Requires Authentication" in "Advanced Sending Parameters" TAB of the SMTP Server page. Then typed in my "Login name with my ISP" and the "Password".

Also, don't forget to put the DNS Servers of your ISP in DNS1 and DNS2 Tabs.

Regards.
