In our old email system (Groupwise) our staff could look at their sent mail and see if a message had been opened/read. Is that possible with this software? Or is there a way to set a preference or something so that the sender is notified when the recipient opens the mail?
I assume your are using the application "Mail" if you are this is how you can do it.....
Request Read Receipts in Mac OS X Mail
To make Mac OS X Mail request a read receipt for every message you send:
Open Terminal.
Type "defaults read com.apple.mail UserHeaders".
Press Enter.
If that command returns "The domain/default pair of (com.apple.mail, UserHeaders) does not exist":
Type "defaults write com.apple.mail UserHeaders '{"Disposition-Notification-To" = "Name <email@address>"; }'" (excluding the outermost quotation marks) and replace Name with your name and email@address with your email address.
The complete line could read "defaults write com.apple.mail UserHeaders '{"Disposition-Notification-To" = "Heinz Tschabitscher <email.guide@example.com>"; }'", for example.
If the "defaults read" command above returns a line of values that starts with "{" and ends in "}":
Highlight the entire line. It might read something like {Bcc = "bcc@example.com"; }, for example.
Press Command-C.
Type "defaults write com.apple.mail UserHeaders '" (excluding the outer quotation marks).
Press Command-V.
Type "'".
Insert '"Disposition-Notification-To" = "Name <email@address>"; ' in front of the closing "}" character, replacing Name with your name and email@address with your email address.
The line might now read defaults write com.apple.mail UserHeaders '{Bcc = "bcc@example.com"; "Disposition-Notification-To" = "Heinz Tschabitscher <email.guide@example.com>"; }', for example.
Press Enter.
Not Only Request but also Respect and Send Read Receipts
Unfortunately, Mac OS X Mail does not respect read receipts. If you get an email requesting a read receipt, nothing special happens.
Using some JavaScript and Mail rules, you can mimic some of the behavior and send simple receipts upon request. These do not fully conform to the standard and will not be interpreted as read receipts by the sender's email program. Of course, the plain language acknowledgment of receipt will still be useful.
Disable Automatic Read Receipt Requests Again in Mac OS X Mail
To turn requesting a read receipt for every message back off:
Execute "defaults delete com.apple.mail UserHeaders" at Terminal command prompt to delete all custom headers or set UserHeaders back to what it was before you added "Disposition-Notification-To".
