To preserve quotation marks and escape characters (those preceded by a backslash) in keys
before database lookup, turn off the Strip Quotation Marks from Keys checkbox. (This parameter
corresponds to the -q option on the K configuration line in the sendmail.cf file.)
10. Ordinarily, Sendmail converts a key to all lowercase letters before looking it up in the access
database. If keys in the virtual user table are case-sensitive, turn off the Convert Keys to
Lowercase checkbox to prevent conversion to lowercase. (This parameter corresponds to the
-f option on the K configuration line in the sendmail.cf file.)
11. Click on Submit to change the server configuration (or click on Cancel to cancel the changes
and return to the Configure Sendmail Server menu).
When the Suppress Errors in the Absence of the Database File checkbox is not checked, the
Administration utility checks that the access database file exists (as specified in the Database
File Name field).
If there are no errors, the utility displays a message confirming that the configuration has been
changed, and indicates that the Sendmail server has been restarted.
If there were any errors in the configuration, the Administration utility displays a list of the
errors.
12. To block incoming mail for certain recipient user names, host names, or IP addresses, return
to the Configuring Relaying page (Section : Configuring Relaying) and set the Check for
Blacklist Recipients in Access Database checkbox.
Configuring Checking on Sender's Information
To configure checking on sender's information, follow these steps:
• Set the Accept Mail from Unqualified Senders checkbox when you want to accept messages
that do not include a domain name in the sender's address (that is, the sender's host name is
not fully qualified). If this checkbox is not set, the Sendmail server rejects any message
containing a sender address that is not fully qualified.
• Set the Accept Mail from Unresolvable Domains checkbox when you want to accept messages
that are from addresses that the Domain Name System (DNS) server cannot locate and resolve.
If this checkbox is not set, the Sendmail server rejects any message containing an unresolvable
domain name in the sender address.
Configuring LDAP
You can configure the Sendmail server to identify users based on the information in an LDAP
directory. When you complete the Configure LDAP form during Sendmail server configuration, the
Administration utility creates a K line entry in the sendmail.cf file that defines how the Sendmail
daemon is to search the LDAP directory to authenticate users.
For information on managing the LDAP Directory servers, see Chapter 11.
To configure the Sendmail server to use LDAP, follow these steps:
1. Under Mail on the Manage Components menu, choose Sendmail Server.
2. From the Sendmail Server Administration menu, choose Configure Sendmail Server.
3. On the Configure Sendmail Server menu, make sure that Server is selected and click on
Configure.
4. From the Configure the Sendmail Server menu, choose Configure LDAP.
5. On the Configure LDAP form, check the Enable LDAP Look-Up checkbox to enable the Sendmail
server to look up user information in an LDAP directory. (You can uncheck this checkbox to
disable LDAP directory lookups while retaining the LDAP configuration.)
6. In the LDAP Search Base field, specify the directory in your LDAP tree in which you want to
begin searching. Use a space to separate the entries in this field. For example:
ou=People o=XYZCompany c=US
