With reference to wharriso message above, I just sent a test message from my swbell.net Email which goes via yahoo and it got through. My security system zooms in on the “person” it detects and the attached images are generally less than 100 Kbytes. Most MMS providers seem to limit messages to about 1 Mbyte and generally a text without the MMS arrives telling you it was “too big”. I suspect yahoo and hotmail and maybe outlook are being blocked. swbell.net may be getting through because the domain name is different.
For what its worth, I did an experiment yesterday. I sent “just testing” through my gmail account to <phone number>@tmommail.net and it worked just fine. I tried my yahoo account and I think it bounced, the message never made it. I tried sending with my hotmail email account (many times) and the messages never made it. I just started receiving failure messages about an hour ago, maybe 15 hours later. It seems to me that T-Mobile is blocking hotmail (outlook) and yahoo email accounts.
