The same in the Dutch Outlook: "Re: Betr.: Re: Doorgest.:" for "Re: Re: Re: Fw:" which should probably be just "Re:" then...
I am no AppleScript expert, but based on the samples in /Library/Scripts/Mail Scripts/Rule Actions, this might get you (or someone here at Super User) started. However, this is not at all a working solution, as I don't know how to make Mail persist the changes. The following will change the subject as shown in the message list, but not the same subject as shown above the message when viewing it. Even worse: restarting Mail gives one the old subject again.
I assume one needs to change the actual source of the message, not just the subject. And maybe AppleScript cannot even do that, but it felt like a waste of time not to post my tries here. ;-)
(EDIT: attempts to change the
source property of a message yield
"Mail got an error: AppleEvent handler failed." number -10000... Maybe the actual
.emlx file must be changed on the file system?)
For testing, it's easiest to create a script that runs for the currently selected message. Like: save the following in a text file named, for example,
test-clean-subject.scp and then double-click it to open AppleScript Editor. Then just click the Play button:
tell application "Mail"
set selectedMessages to selection
if (count of selectedMessages) is equal to 0 then
display alert "No Messages Selected" message ¬
"Select one or more messages before running this script."
repeat with theMessage in selectedMessages
-- Of course, handling just one prefix is NOT AT ALL sufficient:
set thePrefix to "Aw: "
set theNewSubject to subject of theMessage
if theNewSubject does not start with thePrefix then
set theNewSubject to text ((length of thePrefix) + 1) ¬
through -1 of theNewSubject
-- Testing only:
display dialog "New subject: " & theNewSubject
-- This only (temporarily) sets the Subject in the message list.
-- Maybe change "source" instead...?
set subject of theMessage to theNewSubject
You might need to click on the message list to actually see Mail changed it. Again: the above does not solve your problem yet! Also, when one figures out how to persist the changed subject, then the search and removal/replace needs to be much more sophisticated than just searching for a single "Aw: ".
For a true Mail Rule, things need to be slightly different. Copy the relevant parts from a working standalone script into the following, save it and then create a new Rule in Mail for each incoming message (or for messages for a specific sender):
using terms from application "Mail"
on perform mail action with messages theMessages for rule theRule
tell application "Mail"
repeat with theMessage in theMessages
-- copy the actual script here...
end perform mail action with messages
end using terms from
