Blocklisting is a useful tool in lowering the amounts of spam you are getting. You can get to your blocklist by logging in to your Sonic mailbox at https://members.sonic.net. Navigate to:

• E-mail
• Spam Filtering
• Welcomelist/blocklist.

A detailed description of how our spam filtering works and how Blocklisting plays it's part can be found in our SpamAssassin article. Welcomelisting goes hand in hand with Blocklisting and does the opposite - blocking specific messages as spam.

Blocklist Address

Blocklisting an e-mail address will help ensure that it doesn't reach your inbox. You can enter a full e-mail address, or use the * symbol to represent a wildcard.

• Blocklist From spammer@example.com | This will only block e-mails from spammer@example.com.
• Blocklist From *@spamdomain.com | This Blocklist will block from all e-mail addresses at spamdomain.com.

By using the drop down at the top of the page and selecting Unblocklist From, you can make exceptions to wildcards. For example, if you get a lot of spam from example.com, but want to make sure that mail from friend@example.com doesn't get tagged as spam:

• Blocklist From *@example.com | Setting the rule to Blocklist everything from example.com.
• Blocklist From friend@example.com | Adding the exception for friend@example.com.

If you Blocklist an address and e-mails continue to show up from the sender, double check spelling and make sure there isn't a contradicting Welcomelist entry. Conflicting entries will cancel each other out and process e-mail as if there were no entries.

Blocklist Subject

Blocklist Subject works very similar to blocklist Address, except it focuses on the subject line of the e-mail instead of the sender's address. The drop down will have the option to Unblocklist Subject.

• blocklist Subject spam | This will block every e-mail with spam in the subject line.
• Unblocklist Subject spamfriend | This will make an exception to the above rule if spamfriend is found in the subject.

It is important to note that the more specific the blocklist entry, the less likely you are to Blocklist legitimate e-mails.

• Example e-mail subject: Free Lasik Surgery
• Don't: Blocklist Subject free | While this will Blocklist the above subject, it will also Blocklist any e-mail that has free anywhere in the subject line.
• Do: Blocklist Subject lasik | This Blocklist entry is more specific and will catch a more refined group of e-mails.

More Lists

Blocklist To checks the To: field in the e-mail. This is useful if you have multiple e-mail addresses pointing to one e-mail box.
