Comcast Email Not Being Received by Recipients but in Sent Folder
Since sometime in January, we've just discovered that one of our Comcast email accounts is sending emails, but they are not being received by multiple recipients. Since we are sending invoices to business clients using this account, this is causing a lot of issues. Comcast phone and chat support is of little help.
How is best to troubleshoot and correct this issue? We are hoping that this forum is being monitored by high level Comcast tech support.
Thank you very much for any help.
