START_deadhosts_help

Dead Hosts:

This parameter is a list of all hosts in the local domain that
no longer exist or are permanently "down" for whatever reason.
This list will only be checked if the local host is a relay
for the local domain.

The contents of this list is determined by the contents of the
file $CONFIGDIR/sendmail.killed.

END_deadhosts_help

START_directdomains_help

Direct Domains:

This parameter is a list of all domains into which the local
host should send mail directly (without the use of any
forwarder, relay, or MX host).

If the local host is a relay or MX host for a particular
domain, the name of that domain must appear in this list.

If the local host is not a relay or MX host, this parameter may
be null.

END_directdomains_help

START_domainrelay_help

Domain Relay:

This is an internal function to configmail that returns
the name of any relay host for the given domain name.

This is not a parameter and cannot be set.

END_domainrelay_help

START_forwarder_help

Forwarder Hostname:

This parameter must contain the name of the host that acts as
the mail gateway between the local network and all foreign
networks.  (As defined by the rootdomain parameter.)

Mail will be sent to the forwarder host whenever the destination
host exists on the "other side" of the mail gateway, or whenever
the local host cannot figure out how to deliver a particular
message.

If no forwarder host exists, this parameter should be empty.
If the local host is the forwarder host, this parameter should
contain the local host's name.

END_forwarder_help

START_localdomain_help
		
Local Domain:

This parameter must contain the full local domain name.

If domain addressing is not used, this parameter should be null.

END_localdomain_help

START_mycanonname_help
		
My Canonical Name:

This is an internal function to configmail that returns
the canonical name of the local host.

This is not a parameter and cannot be set.

END_mycanonname_help

START_pathalias_help
		
Pathalias Database:

This parameter must contain the location of the pathalias
database used for UUCP mail routing.

If the local host does not do UUCP forwarding, or if pathalias
is not used, this parameter should be set to /dev/null.

END_pathalias_help

START_recsubdomains_help

Recognized Subdomains:

This parameter will only take effect if the Gauntlet for IRIX firewall
product is installed on the system.  Most sites with that product
installed will not need to modify this parameter, as the product's
administrative interface takes care of setting this parameter.

This parameter contains the list of local recognized subdomains.  By
recognized subdomains, it is meant that they will not be re-written
out of sender addresses for email being delivered or forwarded by this
system.  For example, if "corp" is a recognized subdomain of the
network, "ficticious.com", mail passing through this system that is
destined for a non-local, i.e., "outside", host will have sender
headers that read user@host1.corp.ficticious.com rewritten to
user@corp.ficticious.com rather than user@ficticious.com.

More than one recognized subdomain can exist.  Only the recognized
portion of the subdomain should be entered, i.e., "corp" rather than
"corp.ficticious.com".  Recognized subdomains will be assumed to be
subdomains of the configmail root domain.

START_relayname_help

Relay Host Name:

This parameter is the hostname or alias used for all relay
machines.

END_relayname_help

START_rootdomain_help

Root Domain:

This parameter defines the boundary between the local and
foreign networks.  All domain names that end in the root
domain will be considered local domains and all hosts that
exist in those domains will be considered part of the local
network.  All other domains will be considered foreign domains
and all hosts that exist in them will be considered to belong
to foreign networks.

All mail addressed to hosts in foreign networks will be sent
to the forwarder (mail gateway) host for delivery.

For example, if the root domain were set to "company.com", the
domains "engr.company.com" and "mktg.company.com" would be
considered to be local, while "othercompany.com" would be
foreign.  Mail to hosts in any of the "company.com" domains
would be delivered without the use of the forwarder host, while
mail to any host "outside" the "company.com" domains would be
routed through the forwarder.

If domain addressing is not used, this parameter should be null.

END_rootdomain_help

START_loglevel_help

Log Level:

This parameter defines the verboseness of sendmail's logging.  
The higher the value the logging will be generated.  Values are
between 0 and 20, with 1 and 9 being standard settings.

END_loglevel_help

START_numcpus_help

Number of CPUs:

This function will return the number of cpus in a system.

END_numcpus_help

START_percpu_help

percpu:

This function will multiply the argument by the number of cpus in the
system.  This allows for scaling of options by the size of a system.

For example the line "Ox|/usr/etc/configmail percpu 10" will set the
the "x" option to 10 times the number of cpus in the system.
