    SMTP transient error: 452 4.3.1 Insufficient system resources

      We're using UTL_SMTP to send emails from Oracle, and about 2 weeks ago (2 days prior to daylight savings) we start seeing an intermittent "SMTP transient error: 452 4.3.1 Insufficient system resources".

      When there's an issue, emails fail from all 3 of our database environments (on separate servers), which leads me to believe that it isn't Oracle's error. But, our Exchange server isn't showing anything in it's Application Event Log, nor it's Protocol Log (although we just changed settings to log more information).

      I'm just trying to rule out Oracle at this point, so we can focus our efforts. I've been looking on Google for the past hour and a half, and I can't find anything which points to anything other than the mail server being the culprit in an error situation like this. But, I thought I'd put this out to the forum just to see if anyone here has some helpful information, and/or can help me determine if the database should stay on the list of items to look into.
