12.5 SMTP Client Authentication
You may want your Postfix server to relay through other servers that require 
SMTP authentication. In addition to requiring passwords on your own server, 
you can configure Postfix to provide login names and passwords when relaying 
mail through other SMTP servers.
You have to provide Postfix with a password file that contains the credentials 
it should use when authenticating to other servers. Entries in the password 
file contain a domain or hostname, username, and password in the form: domain 
username:password. For the domain or hostname, Postfix first checks for the 
destination domain from the recipient address. If it doesn't find the domain, 
it then checks for the hostname it is connecting to. This allows Postfix to 
work easily with sites that have multiple MX hosts that share the same user 
database. Use smtp_sasl_password_maps parameter to specify where your 
password file is.
The client smtp_sasl_security_options parameter works just like server 
smtpd_sasl_security_options (discussed earlier in the chapter) for the SMTP 
servers. If you don't specify any options, the default allows all available 
mechanisms including plaintext but not anonymous logins.
 
12.5.1 Procedure to Enable SMTP Client Authentication
Use the following steps to configure Postfix to provide a login and password 
when relaying mail. In this example, you'll set up two different passwords 
for Postfix to authenticate when relaying through any server for the domain 
ora.com and through a host called mail.postfix.org:
Create a file called /etc/postfix/sasl_passwd with entries for each host, 
login, and password combination you need. Your file should resemble the 
following:
ora.com                 kdent:Rumpelstiltskin
mail.postfix.org        kyle:quixote
Execute postmap on the file:
# postmap /etc/postfix/sasl_passwd
Edit main.cf to turn on client authentication. Notice that you are now setting 
smtp_sasl_auth_enable instead of smtpd_sasl_auth_enable as you did to turn on 
authentication at the server. You must also set smtp_sasl_password_maps to 
point to the password file you created:
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
Reload Postfix so that it recognizes the changes in its main.cf configuration 
file:
# postfix reload
 
Now, when the Postfix SMTP client attempts to relay messages through any of 
the domains or hosts listed in /etc/postfix/sasl_passwd, it will offer the 
corresponding authentication credentials. For example, if your Postfix smtp 
client connects to the server mail.ora.com, it authenticates with the 
username kdent and the password Rumpelstiltskin.
