I have had this issue before and it was strangely unreproducible. *For me* The issue came up because of an error in the transport file. The file had an error for some domain , and when postfix tries to deliver a mail for this domain and is not able to then every other mail picked up by the same qmgr pid is given the "unknown mail transport error" Check your transport file for some obvious errors. I got rid of the error and everything was working fine
