Thank you, Chris. I use ATT service. After a chat session with them, they suggested it was an iphone issue. So, I have reviewed iphone support and found nothing on the problem, and I have Googled the situation and found nothing. I have reviewed all settings in the phone and see nothing that could be causing this problem. The mystery to me is where does this designation originate: the phone, ATT, my Avast or Microsoft anti-virus, or someplace out in the web that has decided I'm a spammer?
Based on an article I read about another email problem that was corrected by deleting and then re-establishing the account on the iphone, I tried that this morning. I think it may have worked, but since my volume of emails is low, it will take some time to know for sure since I'm not sure exactly what triggers the (Bulk) label.
However, since I deleted and then re-established the email account on the iphone, it has stopped sending me bcc's of my sent mail. I went to settings, and the setting is correct, but I'm not getting them. Any thoughts on this one?
