`MILTER`, Mail Filter API for `sendmail`

MILTER, sendmail's Mail Filter API, enables third-party programs to access mail messages as they are being processed to filter meta-information and content. You do not need to build the filter and configure sendmail to use it. This API is enabled by default in version 8.13 of sendmail.

For more details, see the following:

Alternative `sendmail` Commands

The Oracle Solaris release does not include all of the command synonyms that are provided in the generic release from sendmail.org. This table includes a complete list of the command aliases. The table also lists whether the commands are included in the Oracle Solaris release and how to generate the same behavior by using sendmail.

Table 3-5 Alternate sendmail Commands

Versions of the Configuration File

sendmail includes a configuration option that enables you to define the version of the sendmail.cf file. This option enables older configuration files to be used with the current version of sendmail. You can set the version level to values between 0 and 10. You can also define the vendor. Either Berkeley or Sun is a valid vendor option. If a version level is specified but no vendor is defined, Sun is used as the default vendor setting. The following table lists some of the valid options.

Table 3-6 Version Values for the Configuration File

Field	Description
`V7/Sun`	Setting that was used for version 8.8 of `sendmail`.
`V8/Sun`	Setting that was used for version 8.9 of `sendmail`. This setting was included in the Solaris 8 release.
`V9/Sun`	Setting that was used for versions 8.10 and 8.11 of `sendmail`.
`V10/Sun`	Setting that is used for version 8.12, 8.13 and 8.14 versions of `sendmail`. Version 8.12 is the default for the Solaris 9 release. Starting in the Solaris 10 release, version 8.13 is the default. Version 8.14 is the default for the Oracle Solaris 11 release.
