Thank you for the Welcome
Hello I am Nikolaos Karanikolas
I live in Ptolemaida, city of Macedonia in Greece.
I am working in a company with 30 Users.
I allready have 2 Servers with MS Server 2008. Primary and Secondary
Now my Primary Server has this services , Primary Domain Controller,Active Directory,DNS,File Server,Print Server,DFS with Secondary.
For Routing,Firewall,Proxy,VPN,DHCP i use pfSense
For Hypervisor i use Proxmox
For Backup i use OpenMediaVault

Now i find NethServer because I am looking for alternative to MS Exchange server and MS Outlook client.I don’t have MS Exchange server and i don’t want it.I want local email server that it will work as email client.
In more detail, I want the local email server to download and store the email from multiple email domains and acoounts.

I have tested Zimbra and Zentyal solution but it didn’t support multi-SMTP for one account, like MS outlook client.

Example:
User login as demo@companyA.com and that user can send and recieve from
user1@gmail.com
demo1@companyA.com
demo2@companyA.com
demo@companyB.com

Is this possible with Nethserver (SelfHosting)?
I have not finish with testing of Nethserver yet.
