Sendmail 8.11.1 Release Notes

IMPORTANT: ‘Virtual Hosting’ feature provides better support for ISPs that offer
queueing services to dial-up customers as queue-runs no longer wait for the dial-up
server connection attempts to time out.
• LDAP-based Routing
This feature can be used to implement the LDAP-based re-routing. This provides
a method to re-route addresses with a domain portion in class {LDAPRoute} to
either a different mail host or a different address. The domains can be added to
the class {LDAPRoute} as given in the examples below.
Ensure that you setup a domain for LDAP routing. Assume that your domain is
“yyy.com”. Add the following line in the sendmail.cf file:
C{LDAPRoute}yyy.com
or
F{LDAPRoute}/etc/mail/ldap-domain-file
where /etc/mail/ldap-domain-file contains the domains.
The LDAPDefaultSpec option in the sendmail.cf file sets the default LDAP map
specification. This needs to be set before defining LDAP maps. The settings will
be used for all LDAP maps unless they are specified in the individual map
specification (’K’ command). By default, it appears in sendmail.cf file as follows:
O LDAPDefaultSpec=-h localhost
localhost can be replaced by your LDAP server name.
The following are the switches commonly used by most applications:
1. ‘-b’ - ldap search base
“Directory” in ldap “tree” where the search begins. For example,
-b “o=hp.com”
2. ‘-d’ - bindDN
The BindDN parameter is used to specify the DN value for the LDAP bind
request. For example,
-d”cn=ldap://:389,dc=edat104,dc=atl,dc=hp,dc=com”
3. ‘-h’ - ldap servers
Space separated string of servers which support ldap at your site. For example,
-h “ldap1.hp.com ldap2.hp.com”
4. ‘-p’ - port numbers
Port numbers where ldap service is available. For example,
-p 33333
