Subject:    Remove duplicate header 'MIME-Version'

Hello Group, 

I have configured Postfix as a relay to forward all messages to the AWS
SES mail service. 

SES bounces some messages with the following error: 

status=bounced (host email-smtp.eu-west-1.amazonaws.com[52.48.248.62]
said: 554 Transaction failed: Duplicate header 'MIME-Version'. (in reply
to end of DATA command)) 

These messages are sent by a scanner and I have no influence on the
scanner configuration. 

Is there a way to remove the duplicate header in Postfix? 

Alternatively, is it possible to remove the MIME-Version header(s)
altogether? Would this break the message (or the mail client from the
recipient)? 

Thank you, 

Lucas
