I would really need some help! I'm starting my own reseller service. I'll offer domainnames with mailboxes. For this I will rent some webspace with cpanel an WHM. I then can be part of any domain name reseller programm where I register the domains. I just have to do url forwarding for the domain names to the webspaces I give to the clients. I think until here it is fine.
Now my question: how does it work with the emails? If I register domain names for my clients, how do i manage it that the emails I will give to them have the domain name inside (email@example.com). I will create the mailboxes on my reseller-webspace. I think email-forwarding isn't the solution because they would just receive the emails sent to their new firstname.lastname@example.org
but they won't be able to send through it. If i'm right with this, how can I manage it?
