On RHEL-family systems, sendmail will be replaced with postfix.

Installs the postfix package and manages the service and the main
configuration files (/etc/postfix/main.cf and
/etc/postfix/master.cf). See Usage and Examples to see how
to affect behavior of this recipe through configuration.
For a more dynamic approach to discovery for the relayhost, see the
client and server recipes below.
Use this recipe to have nodes automatically search for the mail relay
based which node has the node['postfix']['relayhost'] role. Sets the
node['postfix']['relayhost'] attribute to the first result from the
search.
Includes the default recipe to install, configure and start postfix.
Does not work with chef-solo.
Sets up the system to authenticate with a remote mail relay using SASL authentication.
To use Chef Server search to automatically detect a node that is the
relayhost, use this recipe in a role that will be relayhost. By
default, the role should be "relayhost" but you can change the
attribute node['postfix']['relayhost_role'] to modify this.
Note This recipe will set the node['postfix']['mail_type'] to
"master" with an override attribute.
Manage /etc/aliases with this recipe. Currently only Ubuntu 10.04
platform has a template for the aliases file. Add your aliases
template to the templates/default or to the appropriate
platform+version directory per the File Specificity rules for
templates. Then specify a hash of aliases for the
node['postfix']['aliases'] attribute.
http://wiki.opscode.com/display/chef/Templates#Templates-TemplateLocationSpecificity
On systems that should simply send mail directly to a relay, or out to
the internet, use recipe[postfix] and modify the
node['postfix']['relayhost'] attribute via a role.
On systems that should be the MX for a domain, set the attributes
accordingly and make sure the node['postfix']['mail_type'] attribute
is master. See Examples for information on how to use
recipe[postfix::server] to do this automatically.
If you need to use SASL authentication to send mail through your ISP
(such as on a home network), use recipe[postfix::sasl_auth] and set
the appropriate attributes.
For each of these implementations, see Examples for role usage.
The example roles below only have the relevant postfix usage. You may have other contents depending on what you're configuring on your systems.
The base role is applied to all nodes in the environment.
name "base"
run_list("recipe[postfix]")
override_attributes(
"postfix" => {
"mail_type" => "client",
"mydomain" => "example.com",
"myorigin" => "example.com",
"relayhost" => "[smtp.example.com]",
"smtp_use_tls" => "no"
}
)
The relayhost role is applied to the nodes that are relayhosts.
Often this is 2 systems using a CNAME of smtp.example.com.
name "relayhost"
run_list("recipe[postfix]")
override_attributes(
"postfix" => {
"mail_relay_networks" => "10.3.3.0/24",
"mail_type" => "master",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
)
The sasl_relayhost role is applied to the nodes that are relayhosts
and require authenticating with SASL. For example this might be on a
household network with an ISP that otherwise blocks direct internet
access to SMTP.
name "sasl_relayhost"
run_list("recipe[postfix], recipe[postfix::sasl_auth]")
override_attributes(
"postfix" => {
"mail_relay_networks" => "10.3.3.0/24",
"mail_type" => "master",
"mydomain" => "example.com",
"myorigin" => "example.com",
"relayhost" => "[smtp.comcast.net]:587",
"smtp_sasl_auth_enable" => "yes",
"smtp_sasl_passwd" => "your_password",
"smtp_sasl_user_name" => "your_username"
}
)
For an example of using encrypted data bags to encrypt the SASL password, see the following blog post:
Examples using the client & server recipes
If you'd like to use the more dynamic search based approach for discovery, use the server and client recipes. First, create a relayhost role.
name "relayhost"
run_list("recipe[postfix::server]")
override_attributes(
"postfix" => {
"mail_relay_networks" => "10.3.3.0/24",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
)
Then, add the postfix::client recipe to the run list of your base role or equivalent role for postfix clients.
name "base"
run_list("recipe[postfix::client]")
override_attributes(
"postfix" => {
"mail_type" => "client",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
)
If you wish to use a different role name for the relayhost, then also set the attribute in the base role. For example, postfix_master as the role name:
name "postfix_master"
description "a role for postfix master that isn't relayhost"
run_list("recipe[postfix::server]")
override_attributes(
"postfix" => {
"mail_relay_networks" => "10.3.3.0/24",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
)
The base role would look something like this:
name "base"
run_list("recipe[postfix::client]")
override_attributes(
"postfix" => {
"relayhost_role" => "postfix_master",
"mail_type" => "client",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
)
