The m4 program cannot rebuild the mail files. [/snip] ...not right away correct, the m4-command does rebuild sendmail.cf. but you should do this in the final directory. so better cd to /etc/mail/ and then do m4 sendmail.mc>sendmail.cf so, if you changed it in your sendmail.mc, this should help you. BTW i prefer a reload of sendmail after doing the changes. Some workaround for the starting of sendmail: do as root -> chkconfig list sendmail you will see a on/off-switch of each runlevel. if its everywhere 'off', turn it on with: -> chkconfig --level 345 sendmail on this turns sendmail on for runlevels 345. if you get an error-messages, that you cannot do this, do: -> chkconfig --add sendmail this adds sendmail to /etc/init.d. now you can redo chkconfig --level....... this will start sendmail automatically on the next reboot.
