hello all, i'm running exchange 2000 and yesterday and ONLY yesterday some of my users were unable to receive emails from outside sources. ie. @yahoo.com? I'm not 100% sure what i should be looking for, i checked the event viewer on exchange and it yielded no results? today all is well and emails are flowing like the mississippi but the emails from yesterday never came through? i'd actually like to know where those emails went? the outside world people that sent emails to us yesterday got not bounce back reply or anything? Yes emails is back up, i mentioned earlier, but the emails from yesterday are no were to be found?
