Understanding Sender ID
Sender ID was a joint development effort between Microsoft and other industry companies
in an effort to combat spam. It is a cost - free authentication solution that uses the
Sender Policy Framework (SPF). How this is accomplished is the administrator creates
an SPF record that contains the IP address of all external - facing email servers and the
MX record of your email server. How does this work?
1. Email is sent to your domain.
2. Your mail relay accepts the message and performs an SPF record lookup
in DNS.
3. If the sending mail server ??™ s name and IP address are correct it is sent on. If
they fail verification, this message may be deleted, blocked, or sent to the junk
folder. This works in part with the Anti - Spam stamping.
