The recommended method to make changes is to modify /etc/mail/sendmail.mc, and various m4 files, then run the m4 macro processor from within /etc/mail as follows: m4 m4/cf.m4 sendmail.mc > sendmail.cf A full explanation of the files to modify, and the available parameters can be found in /etc/mail/README. To automate the running of Sendmail at startup, install the /etc/rc.d/init.d/sendmail init script included in the package. sendmail make install-sendmail The -qNm option to sendmail, where N is number of minutes, controls how often Sendmail will process the mail queue. A default of 5 minutes is used in the init script. Individual workstation users may want to set this as low as 1 minute, large installations handling more mail may want to set it higher.
