seek opportunity to cooperate in Exchange alternative product

[yangsongyi]

Hi, forum administrator, I am a developer of linux system. I have developed a native MAPI system, which means you can use the system instead of microsoft Exchange server, 100% compatible with outlook anywhere. It's all open source. Please take a look at https://github.com/steep-system/STEEP_SYSTEM and maybe you can install a system for a test. If you have interest in our system, maybe we also can add some accounts for you in our system.  I'm looking forward your response. please send me email by yangsongyi@ee-post.com
