Hello everybody, I've been working on debian 9 installation with virtualmin, I configured postfix & amavisd-new to use the disclaimer feature (as signature) as we need to configure this for multiple e-mails on multiple device and I did wanted some server based control over this and also because it's much more easier for any user (as they don't need to do anything ) Everything is working great + DKIM also, but now I'm stuck with another problem. I need to use image attachment for my mail signature, as I can see this is the most "working" use of image in emails, I know it's not perfect but every other solution cause much more compatibility and/or blocked image on mail clients or webmail. I found a way to use altermime to attach file to a mail with this script : Expand: addAttachFilter.pl Code: #!/usr/bin/perl $mime = "desconocido"; $boundary = "desconocido"; $estado = 0; #0 Procesando cabecera #1 Procesando cuerpo mime alternative #2 Procesando cuerpo mime mixed o related #3 Procesando cuerpo mime no alternative mixed o related #Copy, paste and replace for each attachment file. sub printLogo { print " Content-Type: image/jpeg;

I never manged to make it work without using amavisd-new) so I cannot use this script and my skills in coding are close to zero in this field :S So here's my questions Is there any way to configure amavisd-new to use this script and/or auto attach file in specific outgoing emails ? Or is there anyway to use altermime only but with a working DKIM signature. Thanks for the help !
