In fact, anything around that time is curiously absent from the log. Did you neglect to post full log entries? grep that queue ID out of the log file and see what you see. > what the deal is with "did not issue MAIL/EXPN/VRFY/ETRN" as searching > and searching and looking at the solutions I've found so far don't apply I'm going to bet that you're using check_smtp or check_tcp from nagios to monitor this mail server every 5 minutes. Those plugins don't initiate a full SMTP transaction so sendmail complains. They're safe to ignore. > but again if I mail out from the nagios system using the mail command it > works yet email through nagios doesn't work. > > Any ideas? Mail001.youmail.com accepts the message but does something bad with it afterward. You should see what in the maillog on that machine. -- Marc ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
