I have Google and recently had a problem, and I think it originated at the same time when someone tried to open a credit card in my name. After I notified the credit bureaus of a fraud attempt, I changed all of my passwords for everything, but I might have forgotten Google. Found out quite by accident that a good deal of the emails I was sending never made it to the recipient, yet as far as I can tell, I was receiving everything. I never would have known except for the fact that my SIL in FL called me and asked me what the (expletive) my problem was, and why wasn't I answering her mails. I was - she just wasn't receiving them. Fixed now tho............I think.
