How to filter/check outgoing email BEFORE it is sent?
I want to write a set of rules to check outgoing email *before* it gets sent. For example: I have 2 contacts with very similar names and autocomplete occasionally means that I send an email to the wrong person. I want to be able to avoid potentially troublesome situations by specifying that an email with certain keywords never gets sent to specific addresses. I'd like a warning to pop up, or just to have the email shunted into a special local mailbox, if it meets certain conditions prior to being sent out. I am using Apple Mail and Outlook 2011 with an Exchange server. Is there any mail client, or script or extension that will allow me to check emails for specific things before they are sent out?
