What's New With Mail Services

This section provides information about new features in various Solaris releases.

Changes in this Release

The following changes have been made in the Solaris 10 7/10 release release:

• The default version of sendmail has been updated to 8.14.

• The sendmail instance was split into two instances to provide better management of the traditional daemon (svc:/network/smtp:sendmail) and the client queue runner (svc:/network/smtp:sendmail-client).

• 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 or loopback SMTP connections. For instance, mail from a cron job or between local users would be accepted. 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.

Changes in the Solaris 10 1/06 Release

Starting in the Solaris 10 1/06 release, sendmail supports SMTP using Transport Layer Security (TLS). For more information, see the following:

• Support for Running SMTP With TLS in Version 8.13 of sendmail

• How to Set SMTP to Use TLS

Administrative actions on this service, such as enabling, disabling, or restarting, can be performed by using the svcadm command. The service's status can be queried by using the svcs command. For more information about the Service Management Facility, see the smf(5) man page and Chapter 18, Managing Services (Overview), in System Administration Guide: Basic Administration.
