Install and configure mailcatcher for Rails project
Install and start mailcatcher
Type in terminal next commands:
$ gem install mailcatcher
$ mailcatcher
The output to the terminal will be like this
Starting MailCatcher
==> smtp://127.0.0.1:1025
/home/artem/.rvm/gems/ruby-2.6.0@mailcatcher/gems/thin-1.5.1/lib/thin/server.rb:104: warning: constant ::Fixnum is deprecated
==> http://127.0.0.1:1080
*** MailCatcher runs as a daemon by default. Go to the web interface to quit.
Add this config to you environment file, for example: config/environments/staging.rb
config.action_mailer.default_url_options = { host: 'example.com' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = { address: '127.0.0.1', port: 1025 }
One of the known problems: NOT USE localhost since it can be resolved on ipv6 address
# config.action_mailer.smtp_settings = { address: 'localhost', port: 1025 }
# config.action_mailer.smtp_settings = { address: '::1', port: 1025 }
