Is it necessary to manually rebuild a sendmail.cf file or is this done automatically on service restarts?
Solution 1:
In CentOS you do:
/etc/mail/make
service sendmail restart
You also need to have package sendmail-cf installed. A simple restart does not rebuild the .cf from the .mc.
However (and I am looking at a CentOS 6 machine) the init script calls the routine updateconf upon starting sendmail, so there in 6.x you only restart. What is the out put of
grep make /etc/init.d/sendmail
in your machine?
In Debian sendmailconfig rebuilds the .cf if needed before restarting it.
