Hmm. This is theoretical and untested but according to this:
Many mail clients have the option of marking an outgoing message 'high
priority' or 'urgent.' In Mail.app, such messages show up in the Inbox
with two exclamation marks (!!) in the flags column. If you want to
sort messages by the flags column, so that messages you flag yourself
are at the top, all high priority messages you have ever received will
also be at the top of the inbox.
Mail.app currently has no way of removing this flag from emails you
have received (as noted in this Apple discussions thread.). The
following shell script allows you to unset the priority status of all
the emails you have ever received, so that no emails in your inbox
have '!!' next to them any more:
sqlite3 ~/Library/Mail/'Envelope Index' 'update messages set flags = flags | 196608 where flags & 196608 != 196608;'
You can save this as an AppleScript by opening AppleScript Editor and
entering the following:
do shell script "sqlite3 ~/Library/Mail/'Envelope Index' 'update messages set flags = flags | 196608 where flags & 196608 != 196608;'"
You get set this to run when mail receives an email marked with high priority:
- Save your script to `~/Library/Application
- Scripts/com.apple.mail` Mail > Preferences > Rules > Add Rule
any of the following conditions are met
Priority is High
- Preform the following actions:
