Sending email from my comcast.net account not working

My email either fails to send or when it gets sent is delivered with hours of delay from my iPhone for my Comcast’s.net email account.

Having the same issue. I can recieve fine just can't send. Tried reloading outlook and checking settings. Tried different email app. Receive fine, just can't send. Issue also exists on ipad, so it's a Comcast issue for the outgoing server.
