Monitoring Running Tasks

How can I…?
Windows 2000/XP/2003 machines have a built-in IP security mechanism called IPSEC (IP Security).

Your domain name is	mydomain.com
Your e-mail is handled by: There are 2 MX records defined in the DNS	199.199.199.1 199.199.199.2
Your web address is: This refers to your A record	199.199.199.3 199.199.199.4
Other SMTP servers on your network:	199.199.199.5 199.199.199.6

You can enter the following SPF record, which is a TXT record in the DNS like:

​"v=spf1 a mx ip4:199.199.199.5 ip4:199.199.199.6 -all"

This entry tells the recipients SMTP server that an email where the sender’s address contains “mydomain.com” can only come from certain IP addresses.

If any other IP address is used to send message the recipient can reject it.

If any other IP address is used to send message the recipient can reject it.
