HP-UX Mailing Services Administrator's Guide (B2355-91064)

Relay mail from
You can use this option to facilitate relaying through a user machine. The sender name,
which is listed as RELAY in the access map (tagged with From:), can be specified using
this option. The domain portion of the mail sender is also checked when the optional
argument domain is provided.
Delay checks
This option delays the anti-spam checks by Sendmail until it issues the SMTP
RCPTcommand. Mail from certain addresses that might have been blocked by other
anti-spam checks are received. In these cases, deferred checks are not done.
By using delay_checks, the rulesets check_mail and check_relay are not called
when a client connects or issues a MAIL command, respectively. Instead, those rulesets
are called by the check_rcpt ruleset; they are skipped if a sender has been
authenticated using a trusted mechanism, for example, one that is defined via the list
of AuthMechanisms. If check_mail returns an error, the RCPT TO command is
rejected with that error. If it returns some other result starting with $#, then
check_relay is skipped. If the sender address (or a part of it) is listed in the access
map and it has a RHS of OK or RELAY, then check_relay is skipped.
Ldap Routing
You can use this option to implement the LDAP-based email recipient routing. This
provides a method for rerouting addresses with a domain portion in class {LdapRoute}
either to a different mail host or to a different address.
For more information, see “LDAP-Based Routing” (page 68).
Milertable
This option includes a "mailer table" which can be used to override routing for particular
domains (which are not in local host names).
Genericstable
If the genericstable is enabled and GENERICS_DOMAIN or GENERICS_DOMAIN_FILE
is used, this feature will cause addresses to be searched in the map if their domain parts
are subdomains of elements in class {G}. For more information, see “Creating
Domain-Specific Aliasing Using Virtual Hosting” (page 66).
Virtusertable
If the virtusertable is enabled and VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE
is used, this feature will cause addresses to be searched in the map if their domain parts
are subdomains of elements in class {VirtHost}. For more information, see “Creating
Domain-Specific Aliasing Using Virtual Hosting” (page 66).
