Exchange Type Mail Solution
We currently use pop3 mail accounts but some users have multiple devices and would like to get their mail on PC, laptop, tablet or phone. Is there an MS Exchange type solution that I can host on DO? I would think that there would be but I'm new to this community and not sure how to implement it. We have <20 mail accounts and would like the flexibility of Exchange but without the prohibitive cost. Any suggestions? Thanks in advance.
