Can you explain the remedy? I'm not seeing on this forum how you fixed the problem. I regularly need to send a total of about 350 messages to a group. The group is separated into distribution groups of 45 and I send to just one distribution list at a time so as not to exceed 100, per Comcast rules. I do not exceed the message size limit, either. The messages look like they send but they are not received. I use Outlook, but Outlook is not the problem. To experiment, I tried sending the same message to my distribution groups directly from xfinity instead, and it was equally unsuccessful! im not a spammer and I am SO FRUSTRATED that no one at Comcast can solve this for me. I've spent many hours on the phone with Comcast to get this resolved and it still is not.
