My problem is :
Some of my clients are receiving a disfigured e-mail with a gray box which takes up about 90% of the screens with the e-mail squashed on the left-hand side.
Steps I have tried to fix the problem: We have sent e-mails to various accounts as a test and the e-mails were rendered correctly. We have asked one client to forward the e-mail to us who received a disfigured e-mail. It appears that the e-mail is converted to an image since I could copy it in Thunderbird as an image and paste it into LibreOffice Writer. See the screenshots on how the e-mail appears in Mautic and how the client receives it.
