HI,
I am trying to test SMTP-> MMS gateway and I am getting mixed results. First, text messages works both ways no problem at all. Second, I am trying JPEG attachments, anything around 60kb will be delivered to my T68i as corrupted, anything small (15Kb) will be properly resized to feet my screen and delivered. Now, outgoing messages; text works no problem at all. Images form the phone, or forwarded MMS messages sent to e-mail recipient are bouncing back with a message complainin about routing error.
Please advise,
Wojtek

Hi Wojtek,

Without knowing all of the details of your environment, I wonder if the WAP gateway that you are using has size limitations in that area.

The T68i can only receive MMS messages of up to approximately 50K.

Usually, NowSMS will scale the image down to size. But this process could be prevented if the WAP gateway does not send profile information about the phone. And it is possible that the WAP gateway being used has limitations of its own.

I'd probably need to see a debug log to have a better idea of what is occurring.

To create a debug log, manually edit MMSC.INI, and under the [MMSC] section header, add Debug=Yes. Then restart the NowSMS MMSC service, and repeat your sending attempts. Post the MMSCDEBUG.LOG in response to this message.

Then I would suspect a routing error.

You need to configure an SMTP relay host that will relay messages sent by NowSMS. NowSMS connects via SMTP to that server to send any outbound SMTP messages. It sounds like that server is not accepting the messages that NowSMS is submitting.

Again, we can probably get a much clearer picture of what is going on by looking at the MMSCDEBUG.LOG.

All fixed, it was my Exim (SMTP) set for MIME filtering.
Thanks,
Wojtek
