Changes in Version 8.14 of sendmail

The sendmail service has been updated to version 8.14. In addition, here are some of the significant changes to sendmail.

• The system can be configured to automatically rebuild the sendmail.cf and the submit.mc configuration files. The required steps are documented in How to Automatically Rebuild a Configuration File.

• By default, the sendmail daemon runs in the new local daemon mode. The local–only mode only accepts incoming mail from the local host, for instance, mail from a cron job or between local users. Outbound mail is routed as expected, only the incoming mail is changed. The -bl option is used to select the local-only mode, also known as the Become Local mode. For more information about this mode, see the sendmail(1M) man page. For instructions on how to change back to the -bd or Become Daemon mode, see How to Use sendmail in the Open Mode.

• The -t and -u options to the makemap command now work as expected. The delimiter declared with the -t option is used as the delimiter, even with the -u option. Previously a space would be used as a delimiter if the -u option was used, regardless of the delimiter defined by the -t option. See the makemap(1M) man page for more information about these options.
