Well i have a similar problem with fmms. Ever since our great glorious provider changed some settings i receive mms with no receiver. I am kinda trying to fix it by myself but have some issues.
Ok the log says that it cannot get the sender from the push data.

Code:
2016-11-18 07:48:34,742 fmms.__main__: Incoming SMS Push!
2016-11-18 07:48:34,769 fmms.__main__: SRC: MMS:9200

2016-11-18 07:48:37,295 fmms.__main__: fetching mms...
ok i checked the saved binary push file and inside i can see the sender number
Code:
Œ‚˜7D18F876 ‘Š€Ž·ˆô€ƒhttp://mms.telekom.si/MB//7D18F876 ‰€+38641666666/TYPE=PLMN –êFwd: Fwd: Fwd:
i think that the problem is somewhere in the decideNessageHeaderToList fuction as it does not return the sender from the decoded binary data.
Code:
 def decodeMessageHeaderToList(self, data):
        """ Decodes the (full) MMS header data
        
        @note: This B{must} be called before C{_decodeBody()}, as it sets
        certain internal variables relating to data lengths, etc.
        """
        dataIter = PreviewIterator(data)
        
        # First 3  headers (in order
        ############################
        # - X-Mms-Message-Type
        # - X-Mms-Transaction-ID
        # - X-Mms-Version
        # TODO: reimplement strictness - currently we allow these 3 headers 
        #       to be mixed with any of the other headers (this allows the
        #       decoding of "broken" MMSs, but is technically incorrect
           
        # Misc headers
        ##############
        # The next few headers will not be in a specific order, except for
        # "Content-Type", which should be the last header
        # According to [4], MMS header field names will be short integers
        # If the message type is a M-Notification* or M-Acknowledge
        #type we don't expect any ContentType and should break on
        # StopIteration exception
        contentTypeFound = False
        contentLocationFound = False
        while (contentTypeFound == False):
            try:
            	header, value = self.decodeHeader(dataIter)
            except StopIteration, e:
            	print e, e.args
            	break
            if header == MMSEncodingAssignments.fieldNames[0x04][0]:
                contentTypeFound = True
            elif header == MMSEncodingAssignments.fieldNames[0x03][0]:
                contentLocationFound = True
                break
                #pass
            else:
            	try:
			self._mmsMessage.headers[header] = value
			#print '%s: %s' % (header, str(value))
		except StopIteration, e:
			print e, e.args
			break
        
        cType = value[0]
        #print '%s: %s' % (header, cType)
        params = value[1]
        #for parameter in params:
        #    print '    %s: %s' % (parameter, str(params[parameter]))

        self._mmsMessage.headers[header] = (value)
        return self._mmsMessage.headers
The only data that gets returned (i think, still debuging a bit) and is later inserted into the pust_headers table are the following rows adn there is no from row
Code:
3422	624	Message-Class	Personal
3423	624	Message-Size	1719
3424	624	MMS-Version	1.1
3425	624	Expiry	259200
3426	624	Content-Type	('application/vnd.wap.multipart.mixed', {'Start': '<smil>', 'Type': 'application/smil'})
ok here is also the last incoming push message
Code:

so if anyone has any idea... i am kinda new to this python/mms thingy.
Maybe if i would be able to understand the decodeMessageHeaderToList function or how the push message gets decoded i could do a fix but... well am trying to figure out stuff
