Banned Name in Email Message

The Issue -

Users may see this message in their email in box and wonder what has happened - particularly if they are expecting an email message with an attachment

BANNED NAME ALERT The Spam & Virus Firewall found xxx in an email to you.  The Spam&  Virus Firewall has been set to block this type of file.  (where xxx is the issue)

The end result is that the message has been not been delivered, and has been deleted from the mail server.

Why?

The Computer Center has created filters on the Barracuda Spam and Virus firewall which prevents emails with certain attachments - or suspected malware "payloads" from being delivered.  Typically the attachments have a file extension which raises a red flag.

These messages are automatically deleted by the system.

The banned file extensions are:

• ASD
• BAT 
• CAB 
• CEO 
• CHM 
• CIP 
• CMD 
• COM 
• CPL 
• EXE 
• JS 
• JSE 
• MSI 
• MSP 
• NWS 
• OCX 
• PCD 
• PI 
• pif 
• PIF 
• REG 
• scr 
• SCR 
• SCT 
• SHB 
• SHS 
• SWF 
• UUE 
• VB 
• VBE 
• vbs 
• VBS 
• VBX 
• WSC 
• WSF 
• WSH

A Workaround for Attachments which are Legitimate

Say a user reports they are expecting am email from a known source and the source is attaching a zip file to the message.  The Barracuda box will delete any message with .zip attachments.

1. the sender must rename the zip to have a "legal" file extension before attaching the file to their email message.  We recommend using the .txt file extension.  
    
2. Once a the email is received - it should now pass through the Barracuda box without incident - the receiver must:
   1. save the file to their computer
   2. rename the file with the appropriate file extension - in this case ".zip ".
   3. preform the appropriate action on the file - extact, run, etc.
