Hello

Well, the only option other than using your patch I know of is to
increase the AV scan timeout in SMTP server. But I'm afraid that the
sender might give up waiting for the final acknowlegement of DATA. And I
do not want to accept the message before it is scanned (to avoid
backscatter or silent discard of messages).

The speed of scan itself is not a problem, just the reload takes a few
minutes on low-end/old servers.
