Issue:
mail.netvigator.com no longer provide smtp as outgoing server for mail client even connected directly to its ISP service.
Solution:
subscribe no-ip.com Alernate SMTP port (US$19.9 /yr. limited to 150 messages per day)
Tricks:
no-ip.com provide SMTP alternate port with SMTP AUTH but squirrelmail admin cannot handle SMTP AUTH (i couldn’t find a way to input the username and password for SMTP login).
