I posted this in the wishlist thread for 2013, but I wanted to break it out from there.
We have email addresses for services/applications to report errors. Create a flag on the requester record that marks a requester as an automated service and do not send it emails, exempt it from surveys, etc. I want it to be able to file requests, but not for SDP to try to contact it back.
We use the email function to report callhome events from servers, faults from mainframes, and other alerts. What ends up happening is the mail server bounces back and adds a ton of conversation records that are basically useless.
