In the interests of finding out if any of the users on the system were generating these messages, we checked various aspects of the users and investigated one mailing script under one of the users that shows heavy use in the Apache logs. While the check cannot be regarded as comprehensive, it was lengthy and detailed with respect to issues we have seen in the past. We could not attribute any particular user to this problem.
An Abuse engineer and a Security engineer spent well over an hour working on this issue, however, we are only attributing the time spent towards your admin hour for the month of June for this server.
Further time may be spent on this issue by our personnel if you wish, but this would be at a cost of $75 per hour. Please advise if this is desirable, or if you would rather have your admins work on the issue. A rapid response by either party is highly desirable.
