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.
in:trash from:johndoe@example.com
and permanently delete them. Then, select all (and I do mean all of them) and then restore. That's one option, but it will be time-consuming. – Aarthi Apr 8 '12 at 14:48
