Sorry if this has been addressed but I searched and didn't find it. I am using a the Mac mail for comcast account and a few times it has refused to send, saying invalid address. even though it is reply and the address is fine.
Come to think of it, I am not sure any emails have gone out with that account? My business account works fine.
