Sending Mails

Our application is using Symfony Mailer for sending e-mails. The most important configuration is the environment variable MAILER_DSN which is used for configuring the mail system. Locally, we don't use any mailing. In stage and prod systems, this environment variable will be set to our current e-mail setup.

There is also a message for sending e-mails: SendMail. It will be handled by SendMailHandler. It will send the notifications that the user has enabled. The message will be dispatched as part of heartbeat.
