Catches mail and serves it through a dream. MailCatcher runs a super simple SMTP server that catches any message sent to it to display in a web interface. Run mailcatcher, set your favorite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check it out to see the mail that's arrived so far. Shows HTML, Plain Text and Source version of messages, as applicable. Rewrites HTML enabling display of embedded, inline images/etc and opens links in a new window. Command-line options to override the default SMTP/HTTP IP and port settings. Mail appears instantly if your browser supports WebSockets, otherwise updates every thirty seconds. Sendmail-analogue command, catchmail, makes using mailcatcher from PHP a lot easier. Encodings are difficult. MailCatcher does not completely support utf-8 straight over the wire, you must use a mail library that encodes things properly based on SMTP server capabilities.
