Disable UDH Concatenation in OpenSMPP

Hello,

I have a kannel – opensmpp configuration. I have disabled concatenation in kannel by setting `sms-combine-concatenated-mo = false` in group core under kannel conf. Now opensmpp seems to be dropping the messages when it is a multipart message where it doesn’t receive all the parts. We have multiple servers and our partners are sending different parts to different opensmpp servers. I want to disable concatenation and have it just pass the part as is. Is there a way to configure opensmpp to do this?

I read about use_message_payload feature in opensmpp but the documentation doesn’t seem clear for where I can add this.
