Hi all,
i'm start using Courier-mta in the last few days, initially courier-0-43-1 and today i made an upgrade to courier-0-45-4 because of this problem but the situation is still the same.
The problem is introduced when i try to send an e-mail (using OLExpress) with an PDF attachment that was made by Acrobat Distiller and that contain some custom text and images. OLExpress attach it as "quoted-printable", rather than base64 as it happens with others PDF file, and when courier sees it, performs an X-Mime-Autoconvertion from "quoted-printable" to "quoted-printable" that make it unreadable at all with "too few operands" and other error messages by Acrobat Reader. However when i try to sent that attach through others MTAs it will be delivered without problems and without reconvertion.
Now i have two questions:
- why Courier-mta perform a reconversion? and why from "quoted-printable" to "quoted-printable" ??
More than likely because the original message is not properly MIME-encoded.
- is there something to do to disable this feature or to disallow this behavior ?
Fix the mail client.
