(ie, you would need an IMAP server, a Web front end (like Roundcube). The main issue is still going to be calendaring. To be perfectly honest and frank here .. NONE of the Linux based calendaring solutions are good enough (IMHO) for major business use. As much as it pains me to say it, I would personally recommend either office365 or googleapps for mail if I were currently a SysAdmin making recommendations for a company of moderate size. If you HAVE to run a local server, then again, as much as it pains me to say it .. I would use Exchange because of the terrible calendaring on Linux based solutions. There are some suites out there that run on Linux and provide some decent calendaring (zimba, iredmail, kolab, etc.) But my personal experience managing those (and using them) is that they are subpar to the google calendar or exchange calendar solutions. That said, there are a bunch of other pieces (like SPAM filtering, virus scanning, etc.) and all of that adds to the cost of an Exchange solution. And you really can't just ignore those things in 2018 anymore .. so certainly a Linux based on premise solution would be cheaper to maintain. People say that office365 and googleapps solutions are too expensive, but my experience tells me that if you factor in all costs (including hardware and sysadmin time, etc.), and look at quality of service (especially calendaring), those services are competitive.
