i've made somew changes to variuos sendmail files and they don't take effect, i thk i should restart sendmail to re-read all files, but don't know the command to restart, i've tried the following but fails, "no such file or directory":
/etc/rc.d/init.d/sendmail restart

thanks

Which control panel are you using ?

no control panel, just a plain redhat install

Are you sure you are using sendmail and not postfix?

Try -

service sendmail stop
service sendmail start

if that's not working check to see if you have /etc/rc.d/init.d/sendmail present. If you do and stil have problems, check to see if you have a /etc/sysconfig/network file.

what i know is sendmail is my box isn't running as service, its under xinetd which i can it by the command "chkconfig --list"

so "service sendmail xx" doesn't work for me

since its nto a service, /etc/rc.d/init.d/sendmail doesn't existing either

You're sendmail is custom installed?

it isn't custom installed by me, it comes in default from my provider

run the 'setup' program, add it to the system services, and reboot the machine. If its not listed in the system services menu, you will have to create a startup script for sendmail or even try re-installing it.
