I have it turned off at my computer. All other computers on the network use the server anti-virus and antispam software. I can receive their attachments as long as they don't use encryption to send to me. But as soon as they try to send me another file (same type xls, doc, etc) they get stripped. I've looked at the certificate details of 2 on our end and another company I deal with and there is one line of the certificate that is missing on theirs that appears on the others. It's just numbers. (possibly the private key data?) Theirs is the same type/class id from verisign.
