Blocking files from email?
Posted on 09 January 2004 04:53 AM
I keep getting viruses sent to my email ending with file extensions like .exe and .scr. Is there a way to block these using the CNC?
In your CNC Email Manager, if you select any POP email account and then press the "edit" Built-In Filters option, you will see the following:
Enabling this filter, by clicking on it and setting the options, will allow you to block certain attachments. A full explanation of what this filter does is included in the CNC and is reprinted below:
For messages containing a file attachment with any one of the following extensions: .BAT, .CHM, .CMD, .COM, .EXE, .HLP, .HTA, .JS, .JSE, .LNK, .MSI, .PIF, .REG, .SCR, .SHS, .VBE, .VBS, .WSF, .WSH. By avoiding messages with these attachments, commonly associated with executable files, likelihood of receiving virus-containing emails is reduced.*
There is also a Built-In filter ("Attachment Extensions") available that allows you to specify other extensions for attachments with messages that should be bounced, redirected, or deleted, depending on your actual selections.
In addition, the entire FutureQuest Network is protected by a system wide filter that scans all incoming email for known virus signatures and refuses delivery of any email that contains a detected virus.
