Some of my sent emails not being delivered
Using the mail app on my iPhone 12 for my Comcast mail… My sent emails are only being delivered to Comcast email addresses and are not being delivered to non-Comcast addresses. It doesn’t seem to be a Comcast problem (and I’ve talked to them), as all of my sent emails are being delivered if I send them from within the Comcast website. I've tried deleting and then reestablishing my Comcast email account on the iPhone, but the problem persists. Any ideas on what’s causing this and how to fix it?
