When i try to send large file with outlook express ( > 5mb), oe notify me a timeout error (server didn’t responding in 60 seconds). On the log monitor on the mail server, i see the session continue to receive bytes (maybe infinitely, i disconnet the session when the bytes sent is the double of the original file) and strange value about the transfer size (from 10kb to 500kb in one second). When i stop the mail scanning provider, the mail goes fine.
Any suggestion?
regards
