Sendmail Installation and Operation Guide
HoldExpensive [c] If an outgoing mailer is marked as being expensive, don't connect immedi-
ately.
HostsFile=path
[no short name] The path to the hosts database, normally "/etc/hosts". This option
is only consulted when sendmail is canonifying addresses, and then only when
"files" is in the "hosts" service switch entry. In particular, this file is never used
when looking up host addresses; that is under the control of the system gethostby-
name(3) routine.
HostStatusDirectory=path
[no short name] The location of the long term host status information. When set,
information about the status of hosts (e.g., host down or not accepting connec-
tions) will be shared between all sendmail processes; normally, this information is
only held within a single queue run. This option requires a connection cache of at
least 1 to function. If the option begins with a leading `/', it is an absolute path-
name; otherwise, it is relative to the mail queue directory. A suggested value for
sites desiring persistent host status is ".hoststat" (i.e., a subdirectory of the queue
directory).
IgnoreDots
[i] Ignore dots in incoming messages. This is always disabled (that is, dots are
always accepted) when reading SMTP mail.
InputMailFilters=name,name,...
A comma separated list of filters which determines which filters (see the "X --
Mail Filter (Milter) Definitions" section) and the invocation sequence are con-
tacted for incoming SMTP messages. If none are set, no filters will be contacted.
LDAPDefaultSpec=spec
[no short name] Sets a default map specification for LDAP maps. The value
should only contain LDAP specific settings such as "-h host -p port -d bindDN".
The settings will be used for all LDAP maps unless the individual map specifica-
tion overrides a setting. This option should be set before any LDAP maps are
defined.
LogLevel=n
[L] Set the log level to n. Defaults to 9.
Mx value
[no long version] Set the macro x to value. This is intended only for use from the
command line. The -M flag is preferred.
MailboxDatabase [no short name] Type of lookup to find information about local mailboxes,
defaults to ``pw'' which uses getpwnam. Other types can be introduced by adding
them to the source code, see libsm/mbdb.c for details.
UseMSP
[no short name] Use as mail submission program, i.e., allow group writable queue
files if the group is the same as that of a set-group-ID sendmail binary. See the
file sendmail/SECURITY in the distribution tarball.
MatchGECOS
[G] Allow fuzzy matching on the GECOS field. If this flag is set, and the usual
user name lookups fail (that is, there is no alias with this name and a getpwnam
fails), sequentially search the password file for a matching entry in the GECOS
field. This also requires that MATCHGECOS be turned on during compilation.
This option is not recommended.
MaxAliasRecursion=N
[no short name] The maximum depth of alias recursion (default: 10).
MaxDaemonChildren=N
[no short name] If set, sendmail will refuse connections when it has more than N
children processing incoming mail or automatic queue runs. This does not limit
the number of outgoing connections. If not set, there is no limit to the number of
children -- that is, the system load averaging controls this.
