can we customize the message-id in header

Can we update the message-id tag in the header before sent the message ?

Thank you

Message-id is autogenerated at the time it sending emails and it's used for tracking purposes e.g. collecting bounces, spam complaints, and more. If you change it by any chance, your tracking may be effected. And Mumara doesn't allow you to change the message-id during the feeding process, however, you can overwrite it at your MTA side.
