We recently changed hostname on our Fedora server to xyz

and Sendmail logs report like: July 08 00:06:36 xyz sendmail[20506]:

That's fine. But we changed the hostname back to abc but the sendmail still thinks xyz is the correct hostname. Any fix for this?

  • Did you restart the send mail service after changing the hostname? – jsbillings Jul 14 at 13:30
  • Also restart the syslog daemon. – jsbillings Jul 14 at 13:32
