Enable Read Receipts

Here’s how to enable this feature:

Open Terminal, which can be found under ~/Applications/Utilities/. At the prompt, type the following command, then press Return: defaults read com. apple. mail UserHeaders If the command returns an error that reads, “The domain/default pair of (com. apple. mail, UserHeaders) does not exist,” type the following, replacing “Name” and “email address” with your own, and then press Return. For example: defaults write com. apple. mail UserHeaders ‘{“Disposition-Notification-To” = “Name You’re done at this point unless the defaults read command above returns a line of values that starts with { and ends in }. If so, take the following steps to finish setting up read receipt requests. Highlight the entire line. It might read something like {Bcc = “bcc@example. com”; }, for example. Copy that highlighted line with the Command+C shortcut, but don’t paste it yet. Instead, type this (but don’t press Return yet): defaults write com. apple. mail UserHeaders Put a space at the end of the line, enter a single quote, and then paste what you just copied so that it shows up after what was just typed. End it with a single quote. Insert “Disposition-Notification-To” = “Name “; ’ in front of the closing } character, again replacing Name with your name and email@address with your email address. Press Enter. The line might now read like this: defaults write com. apple. mail UserHeaders ‘{Bcc = “bcc@example. com”; “Disposition-Notification-To” = “John Doe “; }’

Disable Automatic Read Receipt Requests

Turning off this setting is just as easy. As above, open Terminal again. Type the following, then press Enter:

defaults read com.apple.mail UserHeaders

defaults write com.apple.mail UserHeaders ‘{“Disposition-Notification-To” = “Name

defaults write com.apple.mail UserHeaders

defaults write com.apple.mail UserHeaders ‘{Bcc = “bcc@example.com”; “Disposition-Notification-To” = “John Doe “; }’

defaults delete com.apple.mail UserHeaders
