This problem has already been reported here, but apparently the thread is closed as I was unable to reply there.
When I send an email, the email is not getting received by two addresses. There may be more, but two I know for sure. Other people I send to are receiving. The two that aren't getting received one is a yahoo.com address and the other is a frontier.net address. Also, this is only recent. Everything went through to these addresses prior..
Did you ask those two recipients if they checked their respective Spam folders? The problem might be at their end.
Yes of course I asked that. Check on here the archived discussions on similar problems. And, I have to ask why an email to someone that has my name in their address book would have one of my emails end up in a spam folder? It's a comcast problem that probably will miraculously disappear like so many in the past. I waste my time coming here.
