Inbucket has an OS X Homebrew tap available as jhillyerd/inbucket,
see the README.md there for installation instructions.
You will need a functioning Go installation for this to work.
Grab the Inbucket source code and compile the daemon:
go get -v github.com/jhillyerd/inbucket/cmd/inbucket
Edit etc/inbucket.conf and tailor to your environment. It should work on most Unix and OS X machines as is. Launch the daemon:
$GOPATH/bin/inbucket $GOPATH/src/github.com/jhillyerd/inbucket/etc/inbucket.conf
By default the SMTP server will be listening on localhost port 2500 and the web interface will be available at localhost:9000.
