VERSIONID and OSTYPE

VERSIONID and OSTYPE

VERSIONID(`@(#)sendmail.mc 8.9 (Linux) 01/10/98')

The VERSIONID macro is optional, but is useful to record the version of the sendmail configuration in the sendmail.cf file. So you'll often encounter it, and we recommend it. In any case, be sure to include:

OSTYPE(`linux')

This is probably the most important definition. The OSTYPE macro causes a file of definitions to be included that are good defaults for your operating system. Most of the definitions in an OSTYPE macro file set the pathnames of various configuration files, mailer program paths and arguments, and the location of directories sendmail uses to store messages. The standard sendmail source code release includes such a file for Linux, which would be included by the previous example. Some Linux distributions, notably the Debian distribution, include their own definition file that is completely Linux-FHS compliant. When your distribution does this, you should probably use its definition instead of the Linux default one.

The OSTYPE definition should be one of the first definitions to appear in your sendmail.mc file, as many other definitions depend upon it.
