I'm not getting the warm fuzzies about the Roundcube plugin for ISPConfig. I believe I have everything installed correctly - with great exchanges with @Th0m and his updated documentation. But I've found issues that seem to be show-stoppers, and have noted them in the repo Issues. The devs there seem very slow to acknowledge issues and make changes. I'm not feeling comfortable with the stability or dedication of developers for that specific FOSS. Am I in a minority? Am I not perceiving this correctly? Should I/we be considering alternatives? Should this all "just work"? I'll be happy to look deeper into my installation and do what I can to fix it, but I'm getting the feeling that this is going to be an ongoing struggle. Thanks for comments and suggestions.
