I have developed a application as a smtp server and I set the default route to my application,then I try to send MM from NowSms to my application through MM4. At the beginning, my server will receive the MM right now, but after I sent a few times, there will be a delay(and longer and longer),why?
Note: The previous sending of MM may be quit abnormally, and I found these sending will be retried, can I stop the retry mechanism? Thanks a lot!

Hi bobby,

There are delays when message sending results in an error condition, and retries have to occur.

It's difficult to say what is happening in your specific situation.

I would suggest enabling the debug log in the MMSC, which you can do by manually editing MMSC.INI, and adding Debug=Yes under the [MMSC] section header. Restart the MMSC service after making this change.

Repeat your attempts, and then post the MMSCDEBUG.LOG in response to this message (or send it via e-mail to nowsms@now.co.uk).

P.S. - The only way to stop the retries (which will give up after 24 hours), is to delete the files from the NowSMS VASPQ directory.

Only if one was requested.

An MM4 ack is requested if the SMTP header includes "X-Mms-Ack-Request: Yes".

The ack is normally sent back via SMTP to the address specified in the "X-Mms-Originator-System" header of the request.

Where this MM4_Forward.RES response is sent depends ... as the specs do not cover this very well.

By default, the response is queued for SMTP delivery as with other SMTP traffic that is being sent out by the gateway. (Which means that it will be forwarded to the "SMTP Relay Host" configured on the "MMSC" page of the configuration dialog.)

However, obviously, this is not a good solution for most interconnections.

Therefore, in the dialog where you configure the inbound MM4 connection to NowSMS ("MMSC VASP" dialog), there is a configuration option that is enabled for MM4 connections titled "MM4 Ack Routing:". This setting lists all MM4 outbound routes defined to NowSMS ("MMSC Routing" dialog), and it allows you to specify that any Ack responses will be sent out via that particular MM4 connection instead of via general SMTP.

Normally, you would define an MM4 connection with both an "MMSC VASP" and "MMSC Routing" definition. So this setting is used to link the two definitions together.
