After working with Comcast I still can’t send emails on my Comcast account, but can now receive them.
I can’t send Comcast emails on my iPhone 13, but finally was able to receive them.
I’ve contacted AT&T, Apple Support, and they couldn’t resolve the issue. They sugggested I contact Comcast and they were able to correct receiving emails, but not being able to send emails.
iPhone 13, 15
