The camel-mail-binding quickstart demands a lot of editing of the switchyard.xml. It gives examples in the Readme.md for what to use for sender/receiver, but it might be better if it actually puts in a working gmail configuration (without password). The connection parameter changes demand that the user knows there's a <mail:password/> tag, where to put the secure attribute.

Also, it specifies to edit src/main/resources/switchyard.xml rather than src/main/resources/META-INF/switchyard.xml.
