Sendmail works through sending to a smarthost, but can't find local users.
# sendmail -bv LocalUser@myhost.net LocalUser@myhost.net... User unknown # grep LocalUser /var/log/maillog Sep 8 03:48:30 myhost sendmail: r887mUs3006678: LocalUser@myhost.net... User unknown
# ls /home|grep LocalUser /LocalUser
# grep LocalUser /etc/passwd LocalUser:x:1001:1001:LocalUser:/home/LocalUser:/bin/bash
How can I configure sendmail to find localusers? How should I diagnose this?
