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 sequentially numbered files on disk (hence the name Mail_trap_). You can configure the hostname (default: localhost) and port (default: 2525) for the server and also where the messages get written (default: /var/tmp). Messages will get written to files named smtp0001.msg, smtp0002.msg, and so on. == FEATURES/PROBLEMS:
