Have you read the Qmail-Scanner FAQ? Especially the bit that says:
"SMTP clients hang when sending messages to Qmail-Scanner"
Basically you will need to speed up your mail processing so that this
out-of-your-control Outlook problem doesn't occur. Bigger servers,
faster AV, or run a "raw" Qmail SMTP server for your users - and relay
that mail to the real Qmail-Scanner server. Can be done on the same
server, etc, etc.
