Hi!

I have web server secured by IPsec policy that allowed only port 80 and
443. From my application I need to send e-mail message to SMTP server.

How to create IPSec filter to allow connection to SMTP server and sending
e-mail messages from application? I don't want to install IIS SMTP service
because I only need to send e-mail.

When I configure IPsec filter as follow:
Source address: Any IP Address
Destination address: My Ip Address
Protocol: TCP, 6
>From any port to port 25
Mirrored

and unsigned and assigned IPsec policy I can connect to SMTP server and
send mail. But after server restart connection to SMTP server doesn't work.
If after server restart I unsigned IPsec policy and try to connect to SMTP
server everything work (expected because I remove IPsec policy). After that
when I again assigned policy with SMTP filter connection still work.

But after restart connection doesn't work.

Any sugestion?

Tnx.
