Quoted printable MTA interaction

  • Hi,

    The DKIM signature was working with simple email, but emails in HTML failed. I thought about a problem in the other plugin, but my investigation showed that simple emails failed if they contain a “=”.

    After that, I found that my MTA was forcing quoted printable encoding and this modified the body.
    Problem fixed by addind “$phpmailer->Encoding = “quoted-printable”; ” in public function phpmailer_init( $phpmailer )

    Suggestion : create an option in the interface to allow the admin to change the default encoding of the emails.

    regards,
    Vincent
