Hi, i'm evaluating this product on a Redhat 8.0 based server running qmail and i think that there is some issue on the module avastrelay.
I have file that when attached in a message using MS OUTLOOK generates a mail that after scanning contains bare LF that make qmail angry and the message non deliverable.
I can send the file for testing if you tell me where to send it.
I also suggest that for a future version you add also the subject line
into the virus warning message.
Anyway the product looks promising and if the bugs get ironed out
it can be a good competitor on the market.
