Internal email and outgoing email is fine. Email just stopping coming in around 4pm yesterday. MX records look good. Not blacklisted. Exch database under the 18GB limit. I have restarted the server, as well as the Exchange services plus the Exch connectors. No errors on this server tying to this time estimate. Note: We do have SEP management console on the server and SEP client with A/V only installed on this server. There was a virus defn update right before no more email. I mention this because we have had many problems with SEP on SBS. I'm not sure if the two are related this time or not.
