I tried to create a filter to trash all emails from (!Athletic_Communications@sacredheart.edu) - an email address used by my school to spam us.
After applying the filter to all my old messages, it trashed everything. I guesse the filter system reads a '!' as "not".
Can I roll back the change - or do I have to restore ALL my trashed emails (over 1000) to get back the 500+ that were incorrectly trashed.
