Does anyone actually know how the approval by email functionality links incoming emails to approval tasks? is it the email subject? some other piece of text somewhere? what?
Reason for asking - rather than getting users to reply manually to the email with a specific word to indicate approve/reject, we would ideally like to include pseudo-button links in the OUTgoing email which, when the user clicks on the appropriate one, would automatically reply to IGL, e.g. using mailto.
