In order to deliver emails to users of Redmine, we need to complete the email configuration.
Email configuration of Redmine is contained in the configuration.yml file.

Let’s see a example email configuration first.

production:
email_delivery:
delivery_method::smtp
smtp_settings:
address: smtp.mailserver.com
port:25
domain: mailserver.com
authentication::login
user_name:'redmine@mydomain.com'
password:'mypassword'
Because Redmine is developed with Ruby on Rails, so it’s email configuration is based on Action Mailer Configuration of Ruby on Rails.
delivery_method The mail transport method to be used. Valid settings:
:smtp
:sendmail
:async_smtp
:async_sendmail
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).
address The SMTP server address to be used.
port The SMTP server port to be used.
domain You can specify your HELO domain in this setting.
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)
user_name If your mail server requires authentication, set the username in this setting.
password If your mail server requires authentication, set the password in this setting.
And if you are using a TLS-requiring mail server, you’ll have to add this setting: enable_starttls_auto Valid Settings:
true
false Set this to true if you are using a TLS-requiring mail server.
