drwebd > version-4.30 and exiscan, something changed

Hi,

we use drwebd in combination with exiscan and the av_scanner option.
This works great for *drwebd* up to Version 4.30.

But after upgrading to drwebd 4.31 or 4.32 drwebd stopped scanning the mails
with this error:

Invalid call: files scanning is disabled by license

The License we used and which worked until drwebd-4.30 was a Mailserver License:

File license: None
Mail license: Unlimited

Question:

Has anybody a working installation with exiscan/drwebd-4.31 or later?

Do we need a Fileserver license instead a Mailserver license now?

Greetings,

Matthias
