Q. I have made changes to the configuration of Sendmail but when I run:
# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
I get the following error:
m4:/etc/mail/sendmail.mc:10: cannot open /usr/share/sendmail-cf/m4/cf.m4: No such file or directory
How to fix it?
A. To resolve the above error, you must install the package sendmail-cf
# yum - and install sendmail-cf
