For the past few weeks I have been having a huge problem. Emails that have attachements are not getting through to the intended parties.
I did several tests. Using even a very small file and sending to my non-profit account. Nothing.
I run several groups and when I reply to "accept" a message so it will post to the group and again nothing.
This is crazy and needs to be fixed. I see complaints dating back to 2015 and no answers on any of them.
Then the message was sent properly. It's sounding like the issue is at the other end. Call Comcast security and see if there is any known blocking issue for those domains-------------------

I sent to several different people including myself at another email. When I used gmail to send same items it all when thru. Everything is messed up since they changed the email system.
Emails after I read them still show as unread. The problem seems to be Camcast.
