Why not support "Antimalware Scan Interface (AMSI)"

From what I know it is a protocol supported by many antiviruses and perhaps it could be integrated with SmarterMail...

@Gabriele We do already, that's how our Windows Defender checks work though I haven't heard anything about other antiviruses integrating into that.

@Matt

As far as I know, there are several antivirus vendors that support AMSI.

A short, non-exhaustive list of known antiviruses that support AMSI:

- With-Secure - formerly F-Secure

- Fortinet FortiClient (my First Choice...)

- Kaspersky

- Eset

- Cybersaver

...

I have investigated using the VirusTotal API but as a separate third party process in conjunction with Declude/DR. However, as someone else posted, to do that you have to use their commercial License which is very expensive. The free license is limited to IIRC 500 requests per 24 hours. Also, and this became a deal breaker for us, unless you use the paid commercial license and specifically configure it to NOT include the checks in the public database, the contents of any file updated becomes part of their public database.
