Installation guide

Supplementary Documents bookshelf of the online Tru64 UNIX
documentation.
You can configure sendmail using the mailconfig or mailsetup
applications. During an update installation, the system will attempt to update
your existing sendmail.cf file to comply with this new version. This
updated sendmail.cf is compatible with both new and old version of
sendmail.
To continue using the previous version of sendmail, invoke the following
command as root:
/sbin/init.d/sendmail select old
This will change all links related to sendmail to point to the version
previous to Version 8.0. Once you are ready to use the new version, you
can switch back by invoking the following command:
/sbin/init.d/sendmail select v8.8.8
4.1.7.2 Initial sendmail Configuration
When the system is first booted, after a full installation, the sendmail
software is automatically configured. This takes a noticable amount of time,
and no status message is displayed until the following warning message is
displayed as a result of starting sendmail:
warning: local host name(hostname) is not qualified;
fix $j in config file.
This means the system does not have a qualified name. This is because
neither bind nor mail has been configured. The sendmail program will
continue to operate.
Ignore this warning.
4.1.7.3 Warning Message When sendmail Updates the alias Database
The sendmail program gives the following warning message when it is
started and its alias database is updated:
WARNING: writable directory /var/adm/sendmail
When sendmail initializes the alias database, it checks the modes on
system directories and files to determine if they have been compromised.
Because the permission on the /var directory is 775, the sendmail
program gives a warning message because it expects the permission on /var
