h1. Email Configuration
{{>toc}}
h2. Configuration Directives
This page is a work in progress, the following configuration directives are only a partial list. Please consult "Action Mailer Configuration":http://guides.rubyonrails.org/action_mailer_basics.html#action-mailer-configuration
for detailed information.
h3. authentication
The type of authentication method expected by your service provider.
Valid settings:
* @nil@ (or omit the key) for no authentication
* @:plain@
* @:login@
* @:cram_md5@
(note: if you set this to @nil@ or omit it, you must not include the @user_name@ and @password@ settings)
h3. delivery_method
The mail transport method to be used.
Valid settings:
* @:smtp@
* :@sendmail@
* @:async_smtp@
* @:async_sendmail@
h4. Asynchronous delivery_methods
The @:async_smtp@ and @:async_sendmail@ use asynchronous sends, which means Redmine does not wait for the email to be sent to display the next page. See "Asynchronous Email Delivery":http://redmineblog.com/articles/asynchronous-email-delivery/ for more details. Some SMTP servers have delay period before processing takes place as anti-spam feature, during which time synchronous method will block Redmine ("10 seconds":http://answers.bitnami.org/questions/4421/updating-an-issue-in-redmine-takes-10-seconds could be default value, see also #11376 for more information) .
With this delivery method, smtp configuration is specified using @async_smtp_settings@ keyword:
<pre>
development:
email_delivery:
delivery_method: :async_smtp
async_smtp_settings:
...
</pre>
h2. Example configuration.yml Configurations
h3. Simple Login Authentication (default settings)
<pre>
# Outgoing email settings
production:
email_delivery:
delivery_method: :smtp
smtp_settings:
address: smtp.example.net
port: 25
domain: example.net
authentication: :login
user_name: redmine@example.net
password: redmine
development:
email_delivery:
delivery_method: :smtp
smtp_settings:
address: 127.0.0.1
port: 25
domain: example.net
authentication: :login
user_name: redmine@example.net
password: redmine
</pre>
*If you want to use GMail/Google Apps and other TLS-requiring SMTP servers*, you'll have to add some TLS-related settings :
<pre>
production:
email_delivery:
delivery_method: :smtp
smtp_settings:
enable_starttls_auto: true
address: "smtp.gmail.com"
port: '587'
domain: "smtp.gmail.com"
authentication: :plain
user_name: "your_email@gmail.com"
password: "your_password"
</pre>
Here is an example for Office 365 users (Exchange online). The sender must have an account, or if you want to send from a shared mailbox, the account below must have authorization to "Send As" the sender which is defined in Redmine email notifications settings.
<pre>
production:
email_delivery:
delivery_method: :smtp
smtp_settings:
enable_starttls_auto: true
address: "smtp.office365.com"
port: '587'
domain: "your_domain.com"
authentication: :login
user_name: "email@your_domain.com"
password: "password"
</pre>
However, this will only work with "recent" enough ruby and rails versions (1.8.7 patchset 2xx and 2.3.5).
(See #5814 )
h3. No Authentication
Example for an SMTP service provider with no authentication.
<pre>
production:
email_delivery:
delivery_method: :smtp
smtp_settings:
address: smtp.knology.net
port: 25
domain: cybersprocket.com
</pre>
h3. Using sendmail command
Example for a unix system that uses the @/usr/sbin/sendmail@ command.
<pre>
production:
email_delivery:
delivery_method: :sendmail
</pre>
h2. Troubleshooting
h3. Error: "hostname was not match with the server certificate"
If you get this error, there's probably a problem verifying the SSL certificate of your smtp relay. As a temporary fix, you can set this option in the appropriate "email_delivery" section:
enable_starttls_auto: false
h3. Error: "Mail failure - no recipient addresses"
When this error happens, the notification is not delivered to the destination address. Instead, you will probably receive a rejection message on your sender address, where you can see the header of the message sent, containing "From:" fields but not containing any "To:" fields.
This error is common on *Debian* boxes, due to the way _exim4_ is configured by default, which is @"-i -t"@. This configuration tells _exim4_ that the destination address is inside the header of the message. Instead, we need to configure _exim4_ so that the destination address will be retrieved from the command line.
The solution consists on editing your _config/configuration.yml_ and making sure you define @arguments@ containing the string @"-i"@, as shown below:
<pre>
# default configuration options for all environments
default:
email_delivery:
delivery_method: :sendmail
sendmail_settings:
arguments: "-i"
</pre>
The example above employs @:sendmail@ method, which employs @sendmail_settings@. In case you are using @:smtp@ or @:async_smtp@ methods, try @smtp_settings@ instead.
