I use today's Indy 10 snapshot.

The error *only* occurs on certain mails (consistently at that!) that
contain  attachments of  type "Autocad dxf" that are encoded as

The tidmessage loads the file with properties "noencode" and
"nodecode" set to true before I send it through a tidSMTP, so
AFAIK the file should be completely unmodified before being sent.

If I re-name the file to *.EML and send it using Outlook Express
there is no problem at all.

I am at a loss. What can I do?
