Our list owners are not receiving bounced mail errors when the error occurs beyond the immediate VM host, unless the error note is generated by an intermediate deamon such as a mailer serving a cluster. Errors generated directly by the SMTPMX's when a host or user not found are disappearing. What have we configured incorrectly? LISTSERV sends everything out through LMAIL - it seems that when LMAIL passes it to an SMTPMX machine and receives an error it is not able to return the error message to LISTSERV and consequently to the list owner. Does this make sense? What am I missing?
