One of our servers was temporarily listed in the Spamcop blacklist. Though Spamcop itself warns that its algorithm is not perfect and may result in legitimate email being blocked when used as a blacklist, some providers still implement this blacklist. As a result, this listing may have caused some emails to be bounced back to you. You will need to re-send any messages that were bounced due to this block now that the listing has cleared.
