Changing the subject in a received message in Apple Mail


 

In Apple Mail I received a message I wanted to keep but the subject was not specific enough for me.

So I googled how to change the subject of a received email in Apple Mail and found this:

While technically it's possible, it's not trivial. You would have to write an applescript to
search/replace the contents of your subject field and then use apple mail filters and run
applescript based on your rule.
This is commonly done in the unix world via procmail, for example when spamassassin detects
spam, procmail appends SPAM to the email subject message.
it might be better to set up rules based on subject to filter your mail into separate boxes for
organization.

I am not conversant with Applescript so I continued reading and found this:

There is a (somewhat convoluted) way to do it:
To edit a message in a Mac OS X Mail folder:
? Drag and drop the desired message out of Mac OS X Mail onto the Desktop
? Ctrl-click on the message copy on the Desktop. Select Open With > TextEdit from the menu
? Make the desired changes to the message source. To change a message's subject, look for "Subject:" at the beginning of a line starting from the top
? Close TextEdit saving the document
? Ctrl-click on the message on the Desktop again. Select Open With > Mail from the menu
? Now select Message > Copy To followed by the message's original folder from the menu in Mac OS X Mail
? Close the message window
? Delete the message copy from your Desktop, and optionally, delete the original message in Mac OS X Mail

It is convoluted but it works. One caveat - after changing the subject don¡¯t Copy to the original folder - copy to a different folder. Then delete the original and move the copy to the folder you want it in.

I wish there was an app to do this task.
