Much like my last blog, I’ll be focusing on items I’m seeing low utilization on. This week I’ll cover file extension blocking. We’ve given you control over the file attachments that get are allowed to pass through the filter.

Some of you were part of our testing of the software and may have forgotten you set these settings. They’ll be going live, please remember that if you decide you want to now allow these items there is an update cycle that needs to happen and due to the nature of change it takes longer than our usual alias updates and such. So please login to and make the changes you wish to make, there is no need to open a support request for this, this hopefully jars your memory.

There is an “exception list” these extensions we will not allow for deviation from our standards of scanning:

.ade, .adp, .bat, .chm, .cmd, .com, .cpl, .exe, .hta, .ins, .isp, .jse, .lib, .lnk, .mde, .msc, .msp, .mst, .pif, .scr, .sct, .shb, .sys, .vb, .vbe, .vbs, .vxd, .wsc, .wsf, .wsh

This is obviously for the security of your clients.
