All emails for a client's domain is forwarded to my gmail account. They are heavily spam ridden and even with gmail's spam filter I receive 2-3 spam emails pr. hour pr. account - there are at least 10 accounts!
I only need notification (domain transfer related) from one single email address.
How can i setup a filter that only allows that single email address to come through and everything else to be deleted?
Thanks in advance :)
