Adding Email Addresses and Domains to Your Whitelist and Blacklist
The PREFERENCES-->Whitelist/Blacklist page lets you specify email addresses and domains from
which you do or do not want to receive emails.
To whitelist or blacklist senders, follow these steps:
1.
Go to the PREFERENCES-->Whitelist/Blacklist page.
A list of your existing whitelisted and blacklisted addresses appears on this page.
2.
To delete a whitelist or a blacklist entry, click the trash can icon next to the address.
3.
To add an entry, type an email address into the appropriate field, and click the corresponding
Add
button.
Tips on specifying addresses
When adding addresses to your whitelist and blacklist, note the following tips:
If you enter a full email address, such as
, just that user is specified. If you
enter just a domain, such as
yahoo.com
, all users in that domain are specified.
If you enter a domain such as
barracudanetworks.com
, all subdomains are also included, such as
support.barracudanetworks.com
and
test.barracudanetworks.com
.
Mass mailings often come from domains that do not resemble the company’s Web site name. For
example, you may want to receive mailings from
historybookclub.com
, but you will find that this
site sends out its mailing from the domain
hbcfyi.com
. Examine the From: address of an actual
mailing that you are trying to whitelist or blacklist to determine what to enter.
List Type
Description
Whitelist
The list of email addresses or domains from which you always wish to receive
messages. The only time the Barracuda Spam Firewall blocks a message from
someone on your whitelist is when the message contains a virus or a disallowed
attachment file extension.
Blacklist
The list of senders from whom you never want to receive messages. The Barracuda
Spam Firewall immediately discards messages from senders on your blacklist. These
messages are not tagged or quarantined and cannot be recovered. The sender does
not receive a notice that the message was deleted, and neither do you.
The only time a blacklisted email address is delivered is if the same email address
also appears in your whitelist.
