DESCRIPTION:
Mailtrap is a mock SMTP server for use in Rails development.
Mailtrap waits on your choosen port for a client to connect and talks just enough SMTP protocol for ActionMailer to successfully deliver its message.
Mailtrap makes no attempt to actually deliver messages and, instead, writes them into a file (hence the name Mail_trap_). Handy tip: use tail -f to see emails being received.
You can configure the hostname (default: localhost) and port (default: 2525) for the server and also where the messages get written (default: /var/tmp/mailtrap.log).
