Hello,
there had been done a fix for CRLF/LF re-encoding only yesterday,
at a bug [1]. Maybe it's related to your issue.

This is not a good idea by any means, because:
a) smart virus detectors do not depend on extensions, but check actual
content; they are even that smart that they unzip files and check
their inner content too;
b) interpreting binary files as text files can break everything;
some parts can be attached unencoded, then anything on the route
between the sender and the receiver can modify the content, being it
for CRLF or folding/wrapping. This is avoided when they know the part
is application/octet-stream and when it is encoded in base64;
c) if a mail application detects type based on the extension (it can be
a fallback), then it can eventually run associated text editor on the
attachment, which surely leads to issues.
I believe an ideal solution is to provide a link to some public server
with your uploaded executable, rather than attach it to an email, but I
also agree that it's not always possible.
In any case, it would be interesting to see whether changes for [1]
fixed your issue too.
Bye,
Milan
