David,

With 2.0.6.16, which is available from the Declude site, you can turn off the Outlook CR Vulnerability. I have turned off all but a couple of these because of numerous false positive issues.

As far as this message goes, it is almost definitely their antivirus scanning product that munged the headers (X-AntiVirus: gadoyanvirus 0.3), but it could be something else that adds or rewrites headers. They certainly look strange to me, and possibly not RCF compliant outside of the CR issues.

Thunderbird definitely has no issues with this, nor does almost every legitimate E-mail client out there, but people that script E-mail generation (especially PHP stuff) or use obscure products seem to have issues with this frequently enough that it is not worth the trouble. If there was ever an exploit spreading actively in the wild, I would rethink my position. I believe that Microsoft has long since patched the flaw, though it can certainly cause parsing issues in virus scanners that could lead to missing the payloads due to a message that was improperly formatted.

Is it time to drop the Outlook vunerbility test??
