If you have any subscribers at eyenet.eybe.edu.on.ca, you may want to check the validity of their userids. That host fails to return mail to the SMTP MAIL FROM (or Errors-To) address, and postmaster, root, and even Mailer-Daemon (which sends mail) bounce as "not found" users. Perhaps someone knows a way to contact these folks to let them know they have a serious compliance problem. Otherwise, you might want to SERVE out the host until someone identies at least one userid there that functions. /s Murphy A.
