Configuration Directives¶

This page is a work in progress, the following configuration directives are only a partial list. Please consult Action Mailer Configuration
for detailed information.

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)

delivery_method¶

The mail transport method to be used.

Valid settings:

• :smtp
• :sendmail
• :async_smtp
• :async_sendmail

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 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 could be default value, see also #11376 for more information) .

With this delivery method, smtp configuration is specified using async_smtp_settings keyword:

development:
  email_delivery:
    delivery_method: :async_smtp
    async_smtp_settings:
    ...

Example configuration.yml Configurations¶

Simple Login Authentication (default settings)¶

# 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

If you want to use GMail/Google Apps and other TLS-requiring SMTP servers, you'll have to add some TLS-related settings :

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" 

However, this will only work with "recent" enough ruby and rails versions (1.8.7 patchset 2xx and 2.3.5).
(See #5814 )

No Authentication¶

Example for an SMTP service provider with no authentication.

production:
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      address: smtp.knology.net
      port: 25
      domain: cybersprocket.com

Using sendmail command¶

Example for a unix system that uses the /usr/sbin/sendmail command.

production:
  email_delivery:
    delivery_method: :sendmail
