This is not something you can fix yourself. So I'm escalating it to the forum admins for follow-up. Someone will respond to you here in this thread.
CassoM, I'll take a look into your email deletion issue. Please send me a private message (Click ComcastKenF and then click Private Message Me) with your phone number, account address, and full name for assistance.
I'm having the same issue. Some emails show up my iPhone for a second and then are gone without being opened. When I look on the Comcast Email website, the emails are in the trash folder. It doesn't happen for every email but is becoming an issue as important emails are not being delivered to my phone or computer and I have to go into Comcast email website to retrieve from trash.
