Hi,
I have a problem with NIS2010 17.0.0.136, italian version, with Windows 7 Ultimate RC1 x86 and Windows Live Mail (downloaded from Microsoft web site 2 days ago). Outgoing mail scanning is turned on with scanning indicator also on. Sometimes (quite often), appearently in a random manner, outgoing mail are not sent (I have verified it sending me some mails to another account and also because some peolpe didn't receive my mails). The scanning indicator doesn't appear but Windows Live Mail puts the messagge in the Sent messages as usual. I haven't been able to identify a type of attachment which causes always this behaviour. A file previously 'rejected', sent again later, sometimes goes regularly or it isn't sent again. When the scanning indicator appears, mails are regularly sent. The server is SMTP on port 25 with Server authentication on as required by my provider. If I turn off Outgoing mail scanning the mails are always sent regulary. NIS2010 is updated (I am permanently connected to Internet). This problem seems to exists also for Outlook as I found searching the web.
Thanks
