I have a new installation of ISPConfig 3 - 3.0.5.4p5 on Centos 7. This installation is for running a wordpress site. The wordpress site is using PHPMailer 5.2.7 Amavis is bouncing a message sent to a form : ---------------------------------------------------------------------------------------------------- This nondelivery report was generated by the program amavisd-new at host host.com.au. Our internal reference code for your message is 03853-05/Uhq5KcHs2YE3 INVALID HEADER Duplicate header field: "MIME-Version" ---------------------------------------------------------------------------------------------------- What is the best way to fix this ? Regards, Richard
