Add trusted email forwarders to improve spam score
accuracy
Part of the spam score for an email message is calculated using the IP address of the server that the message
was received from. If an email forwarding service is used, the IP address of the forwarding server is used to
calculate the spam score. Because the forwarding server is not the initial source email server, the spam score
can be inaccurate.
To improve spam scoring accuracy, you can enter one or more host names or domain names of email servers
that you trust to forward email to your email server. After you add one or more trusted email forwarders,
spamBlocker ignores the trusted email forwarder in email message headers. The spam score is calculated
using the IP address of the source email server.
Add Trusted Email Forwarders
On the spamBlocker Settings Common tab, you can enter one or more host names or domain names of email
servers that you trust to forward email to your email server.
