I am looking for help to determine what might cause the error "451 Temporary local problem - please try later". The last 2 mornings, we have received this error when sending an email to a distribution list. As far as I can tell, the email does eventually get sent, but we normally don't see this type of error.

It's the SMTP host on the receiving end saying it's got some sort of problem receiving your mail. Probably running into a Graywall since this is typically the error message you will get.
