I have an outlook account that has a distribution list of about 30 emails. About 20 of them are too at&t phones. The rest of them are from various other carriers. All the other carriers messages to through, but at&t's does not. I get no error messaged kicked back either.
Sending to a single at&t phone works fine. My message has under 160 characters, doesn't have any pictures, and is not in HTML format. Is there a limit to how many emails you can send to an at&t phone at one time? If so, is there a way around this? Thanks.
