Email related problems and solutions
Most email problems are caused by non-clean ubuntu installs.
Make sure you installed ubuntu freshly, and after, you installed ehcp directly.
Some email problems may be fixed by ehcp gui->options->”fix mail config”
While solving your problems, follow Howto Debug ehcp: http://ehcp.net/?q=node/771 and keep open log windows.
