ISA 2004 failed to send alert notification by e-mail

Hi All,

I have a ISA 2004 running on Windows 2000 server. I wanted to create a
alerts notification under monitoring section and send through by e-
mail. After filled in detail in SMTP server, From and To. When I click
on the test button, it will prompt me "The simulation was not
completed successfully. No e-mail message was sent."
For further diagnose, I did a telnet and the following was the result.

telnet mail.mailserver.com 25
- 220 mail.mailserver.com
Helo mailserver
- 250 mail.mailserver.com Hello [xxx.xxx.xxx.xxx.], please to meet you
(whatever I type after this line, I will hit 550 5.7.1 Access denied)
Help
- 550 5.7.1 Access denied
Mail from: xxxxx
- 550 5.7.1 Access denied

I did created a new rule and allow all outbound traffic from local
host to external. But the problem is still persist. I hope someone
could guide me. Thank you


Regards,
Alan Lim
