It is a powerful email free software, I like its versatility in platforms and adaptability, allows me to send emails in a simple and complete environment. I can configure it in my Smartphone, I can even add several accounts in my own session of the same domain and others like gmail. Being installed on the servers of the organization, we have greater storage capacity. It's lightweight, friendly and very intuitive. It allows us to send larger emails and limit the mailbox space as a free email as gmail but as a greater range, even if the Internet fails we can send internal emails. Good to change the background of the desktop, whenever the administrator of the service allows it to me, to integrate it with other applications, I create the folders that like, according to my works.
