Recipients are not receiving emails
Lately when I am sending emails from either my iPhone or laptop through my Comcast email they are not going through to some people. It is random as to who this is happening to. I have begun to cc myself and see that they are going out since I am receivng the email however, the receipient is not and it is not in their spam folder.
Can you tell me what I can do to fix this. I do not have my VPN on either.
