I am getting a SMTP error in ISA's log file, which I am assuming it is related to our Exchange server. Here are the descriptions I am getting alerted to:"An unknown SMTP Command" XEXCH50 2096 X-LINK2STATE DROP X-LINK2STATE LAST X-EXPS GSSAPI Is this an ISA issue or an Exchange issue and how are they related? Any ideas, thoughts, etc?
