Junk Mail Filtering: Rejected Email Addresses

WP Enthusiast and WP Professional hosting accounts can use this tutorial if the Email Add On has been enabled.

What is Blocklisting?

Rejecting addresses/subjects is a way to reject emails based on a condition. For example, you may reject an email from a certain address or with a certain word in the subject line. Rejecting addresses is typically used as a way to keep spam from making it into your account.

How Rejecting Addresses Works

When you reject an email address, your mailbox rejects emails with a matching address in the "Return-path" section of the email header. No mail from that address will make it into your inbox until you remove it from the Rejection List.

Rejecting addresses only rejects addresses matching the "Return-path" header, not the "From" address. Using the "From" address for rejected addresses may allow undesired emails into your inbox. 

You can find an email's "Return-path" header by viewing the email's header. See How to Get Email Headers by MXtoolbox. 

You can reject all subdomain addresses from a specific domain by rejecting the following: "@*.domain.com"  Be sure to replace "domain.com" with the domain you want to block.

How Do I Reject Addresses in the ACC?

You can set up rejection rules directly on your mailboxes in the Account Control Center (ACC).

Choose the tutorial that reflects your ACC interface type: 

• Legacy Interface
• New ACC Interface

Not sure what the difference is? See Which ACC Interface Am I Using? 

If you are using the Legacy Interface:

1. Log in to the Account Control Center (ACC) at my.pair.com
2. Click E-Mail in the left sidebar, then click Manage Junk E-Mail Filter Settings
3. Scroll to “Additional Junk E-Mail Filtering Options” section at the bottom of the page
4. Click Add, Remove, or View Rejected Addresses

There are two different ways you can add rejected addresses.

Add a Single Rejected Address

In the first section, under the “Add Rejected Addresses” header, you can add a single address that should be rejected. Next to Rejected Addresses, enter the address into the field. You can add any additional comments in the field next to Comments.

Once completed, click the Add Rejected Addresses button. The address will appear under the E-mail sent with these Addresses will be rejected where possible or marked as “Junk” header.

The address listed in the "Return-path" may differ from the "From" address. Due to this, rejecting the "From" address only may result in undesired email making it into your inbox. See How to Get Email Headers by MXtoolbox for instructions on accessing your email header.

Add a List of Rejected Addresses

You can add a list of rejected addresses in the section, under the “Upload a list of Rejected Addresses” header. Click the Choose File button and select a file with a list of rejected addresses.

The file should be in plain text, with each rejected address on its own line.

When the file has been added, click the Upload button. If the file is formatted correctly, the new rejected addresses will be added to the list under the last header, “E-mail sent with these addresses will be rejected where possible or marked as ‘Junk’” header.

The address listed in the "Return-path" may differ from the "From" address. Due to this, rejecting the "From" address only may result in undesired email making it into your inbox. See How to Get Email Headers by MXtoolbox for instructions on accessing your email header.

How to Remove Rejected Addresses

If you no longer want an address on the list to be rejected, you can remove it from the rejected address list under “E-mail sent with these addresses will be rejected where possible or marked as ‘Junk’” header.

1. Check the box next to the address(es) you would like to remove
   
   If you would like to delete all rejected addresses from the list, check the box next to Check All
2. Click the Remove Selected button
3. Click the Confirm Deletion button.

Once addresses are deleted from the list, they will no longer be automatically rejected or marked as junk.

If you are using the New ACC Interface:

1. Log in to the Account Control Center (ACC) at my.pair.com
2. In the “Account Email Settings” section, find Junk Email Filter Settings and click its Edit button
3. In the “Junk Filter Settings” section, click the More junk email filtering options… button
4. In the drop-down, click the Add, Remove, or View Rejected Addresses option
