D. Sun Enhancements

Sun Microsystems has adopted V8.6 as its standard version of sendmail as of Solaris 2.5. It will adopt V8.8 when it releases Solaris 2.7. Here, we cover Sun's enhancements to V8.8 as planned for Solaris 2.7.

Sun Microsystems has modified V8.7 sendmail to meet three internal requirements. Each new release of Sun supported sendmail must do the following:

• Be backward compatible with old, user configuration files

• Support the advantages of Sun's operating system, such as NIS+

• Allow for easy administration by naive system administrators

To meet these requirements, Sun adopted use of the V configuration command (see Section 27.5, "The V Configuration Command") to indicate to sendmail how the sendmail.cfThe only exception to this is a feature that is available to both V1/Sun and V7/Sun, the Content-Length: header (see Section 35.10.7, Content-Length:). This is used to support Sun's MUA.

you should obtain the V8.8 release from Berkeley (see Section 18.3, "Obtain the Source").
