I read in the forum constantly, but still to Nethserver v7 still some questions.
I want to do the following:
I want to set up a server in the internal network (DMZ) for different external mail domains. The
server itself should have only these external mail domains and the Mails with fetchmail (getmail) to pick up and the respective user. The mailing of these external maildomains (@ outlook.com, @ gmx.net, etc.) should be done via the SMTP of the mailprovider. I also need no firewall etc., since the mailserver is only accessible internally (intranet).
Can I create the user names in the Nethserver already with the respective (external) names of the maildomains?
