Beginning
with V8.12 sendmail, the
vacation program reads the
sendmail program's
configuration file to locate the value of the
MailboxDatabase option (MailboxDatabase). It scans the configuration file looking for
lines that begin with the prefix:
O MailboxDatabase=
If the MailboxDatabase option is undefined, its
default value is pw, which means to look up
mailbox information in the passwd(5) file form
of database. The mailbox database is used to find the home directory,
and user and group IDs for the user. The mailbox database is ignored
if the -U command-line switch is used.
The location of the configuration file is defined at compile time
with _PATH_SENDMAILCF (_PATH...). If you wish to
use a different configuration file, you can do so by specifying it
with this -C command-line switch:
% vacation -C /etc/mail/sendmail.cf.new -i
If the configuration file listed with -C
doesn't exist or is unreadable, the entire
-C directive is silently ignored. If the
MailboxDatabase option is found but specifies an
unknown database, the following error is logged or printed and the
vacation program exits:
vacation: can't open mailbox database: Service unavailable
