Weird glitch with email notifier for Omni IIe

[iJDUB]

So when I set my email as number @ txt.att.net I get the texts. When I set it as number @ mms.att.net it doesn't work unless I click the button TEST. If I purposely send a command to message the MMS address it works fine. If I use the preset notifications it won't send to the MMS but will to TXT...

Any ideas?
