Enhancements to sendmail

The following new features are available in sendmail version 8.12, which is included in the Solaris 9 operating environment:

• A new configuration file, submit.cf

• New command-line options

• New and revised configuration file options

• New defined macros

• New macros that are used to build the configuration file

• New and revised m4 configuration macros

• New compile flags

• New delivery agent flags

• New queue features

• New uses for LDAP

• A method for identifying IPv6 addresses in configuration

• Changes to mail.local(1M)

• Changes to mailstats(1)

• Changes to makemap(1M)

• A new maintenance utility, editmap(1M)

The following details might be of particular interest:

• Per RFC 2476, sendmail now listens for submissions on port 587, a feature that was added but not mentioned, in version 8.10.

• Because the AutoRebuildAliases option is no longer available, newaliases must be run manually now in order for changes to /etc/mail/aliases to become effective. Also, because sendmail is no longer setuid root, only root can run newaliases.

For further information, see the “Mail Services (Tasks)” in System Administration Guide: Resource Management and Network Services. The chapters on mail services provide overview information and procedures for setting up and modifying your mail service. Also provided are procedures for troubleshooting, some background information, and details about the new features.

Version 8.10 of sendmail was first made available in the Solaris 8 4/01 operating environment. Version 8.12 of sendmail is available in the Solaris 9 operating environment.
