Hi
I need to set some of our boxes to send mail through our smarthost. In the sendmail.mc file i have set the smarthost and rebuilt the sendmail.cf file. When i send a mail locally on the box though i get this error
Diagnostic-Code: SMTP; 553 5.1.8 root@localhost.localdomain... Domain of sender address root@localhost.localdomain does not exist
You can give the host a fully qualified hostname in /etc/hosts or /etc/sysconfig/network and that should resolve the problem.
i.e. if the system is 192.168.1.10 then in /etc/hosts have...
192.168.1.10 system system.mydomain.com
Then 'service sendmail restart' and you should be good. There are other Sendmail workarounds but this is how we setup systems that aren't mail servers as such.
Will.
