He will be implementing a new "virus filter" Tuesday morning that should help to clean up the problems we have experienced recently with virus infected files. Please read on and feel free to ask questions if you have any. Thanks Jon Lee From: Mann, Lashley Sent: Monday, June 17, 2002 10:10 AM To: Multiple recipients of list Subject: Attachment filter implementation... Hi All, The test of the attachment filter being used on the NIFL-ESL discussion list has gone well. The filter has caught, as of last Friday (6/14), 34 potentially virus infected messages and stopped them from being distributed to the list membership. There were six additional messages with potentially virus infected attachments caught over the weekend. Based on these results NIFL has directed that the filter be implemented on all discussion lists. To allow you time to notify your lists I will implement the filter on all discussion lists the morning of 6/18. You should let your list members know that file attachments will no longer be allowed through the discussion lists once the filter is in place. The filter will also enforce the "plain text messages only" rule. Email messages sent as MIME attachments or HTML mail will be rejected (these types of emails include the message body as an attachment...hence the filter rejects them). If your list members send messages as or with attachments they will receive a notice from the list server advising them that attachments are not permitted and that they should resend their messages as "plain text" messages. Implementation of this filter will greatly reduce the possibility of virus infected messages being passed through the discussion lists. It will similarly reduce the possibility of virus infected messages being part of the archives. Please note that virus infected messages currently do exist in the list server archives. If users have their subscriptions set to DIGEST format they may receive infected messages when the next digest format message is sent from the list server so they should beware. Once the filter is in place infected messages shouldn't make it into the list server archives (or the on-line HTML archives for that matter). I will attempt to remove the infected messages from the list server archive. If you have any questions please ask. Lee NIFL system/list administrator -- Lashley H.
