Filtering by Sender Email Address
The BLOCK/ACCEPT-->Email Sender Block/Accept page lets you filter messages based on the
sender’s email address.
The following table describes the parameters on this page.
Filter Description
Allowed Sender
Domain/Subdomain
Add any domains or subdomains that you wish to include in your whitelist.
Whitelisting a domain automatically whitelists all subdomains. For
example, adding customer.com allows messages from [e-mail]
as well as [e-mail].
Whitelisted domains/subdomains bypass spam scoring as well as all other
blacklists with the exception of IP block/accept and body/subject filters.
Click Add after adding each entry, followed by Save Changes.
Blocked Sender
Domains/Subdomain
Add any domains or subdomains that you wish to block. Blocking a domain
automatically blocks all subdomains. For example, adding spammer.com
blocks messages from [e-mail] as well as
[e-mail].
Blacklisted domains/subdomains bypass all whitelists with the exception of
IP address/network and domain/subdomain-based whitelists. You can
specify whether the IP/Range should be blocked, quarantined or tagged.
Click Add after adding each entry, followed by Save Changes.
