Whitelisting is a useful tool in making sure that e-mails that are important to you are making it to your inbox and not being marked as spam. You can get to whitelists by logging in to your Sonic mailbox at https://members.sonic.net. Navigate to:
- Spam Filtering
A detailed description of how our spam filtering works and how whitelisting plays it's part can be found in our SpamAssassin article. Blacklisting goes hand in hand with whitelisting and does the opposite - blocking specific messages as spam.
The first option for whitelisting is going to be whitelisting specific e-mail addresses. Enter the e-mail address you would like to whitelist and click the button to add the entry. Going forward, whenever an e-mail from the specified e-mail hits our spam filter, it will be given special treatment to help it reach your inbox. You can also use the * symbol to signify a wild card. For example:
- firstname.lastname@example.org | This will whitelist all e-mails coming in from email@example.com.
- *@example.com | This will whitelist all e-mails from the example.com domain.
You can edit or delete whitelist additions manually. Scrolling down to the bottom of the page will give options to delete all entries or to share settings with all mailboxes on the account (the latter will only show up if logged into the primary Sonic account).
The top drop down offers three additional options to whitelisting. The first, Unwhitelist From, is an easy way to remove specific addresses from a wildcard. For example:
- Whitelist From *@example.com | All e-mails with the domain example.com will be whitelisted.
- Unwhitelist From firstname.lastname@example.org | email@example.com will be an exception to the 1st rule.
- Unwhitelist From firstname.lastname@example.org | email@example.com will also be an exception to the 1st rule.
The above example shows an easy way to whitelist all e-mails from example.com, except for that of firstname.lastname@example.org and email@example.com. The next two options, Whitelist From Received and Unwhitelist From Received work the same as Whitelist From and Unwhitelist From. The difference is that both allow the additional checking of the message headers. The entered string is matched against the reverse DNS lookup used during the handover from the untrusted Internet to your trusted network's mail exchangers. The format that these entries should be entered are as follows:
- Whitelist From Received *@example.com mailserver.example.com
- Unwhitelist From Received firstname.lastname@example.org
- Unwhitelist From Received email@example.com
Whitelist Subject allows you to whitelist any e-mails that come in with keywords in the subject line. Note that the more specific, the better. For example, if you whitelist the subject e, any e-mail that has the letter e anywhere in the subject line will be whitelisted.
- Example e-mail subject: Your Purchase Receipt
- Don't: Whitelist Subject you | Since you is in the subject, the whitelisting would work. However, every other e-mail that has you in the subject will also be whitelisted.
- Do: Whitelist Subject receipt | This will not only whitelist this e-mail, but will make sure that only e-mails of a similar intent are whitelisted.
In the More Lists section, you have the option of adding To-Whitelisting. This will check the To: field in an e-mail. This is useful when you have one or more e-mails forwarding to your Sonic mailbox.There are three levels of To-Whitelisting: Whitelist To, More Spam To and All Spam To. Addresses in the first level may occassionally have some spammish mails blocked, but addresses in All Spam To should never get mail blocked.
- Whitelist To firstname.lastname@example.org | This will whitelist e-mails forwarded from email@example.com to your Sonic mailbox. High SpamAssassin score e-mails will still be blocked.
- All Spam To firstname.lastname@example.org | This will whitelist e-mails forwarded from email@example.com to your Sonic mailbox. This will override high SpamAssassin scores and always make it to your inbox.
At the bottom of this page, there is also a section to allow e-mails via Trusted Networks. You can specify specific IP addresses or ranges. For example, the following example to trust anything that comes from Sonic.net's mail servers:
Trusted Networks 22.214.171.124/25 Trusted Networks 126.96.36.199/30 Trusted Networks 188.8.131.52
