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
