As of approx 19:36, one of our downstream nodes SNYCENVA appears to be bouncing all mail with error message SMTPUSER@SNYCENVA not found where SMTPUSER is listed on the server1 record of the node entry I can't seem to get in touch with anyone at that site - is there anyway I can tell MY listserv not to distribute to that site ? - mike ( rapidly balding !!!! )
