I need advise on how people go about this.
At the moment, I use Exim4u as the web interface to create domains. It allows me to limit the number of users per domain.
GO comes in just as a web interface with all the bells & whistles.
Someone has approached me about managing a Zimbra system, but I thought I liked GO because at the back-end, I am comfortable with Exim+Dovecot.
The challenge with the Exim4u+GO combo is that users need to visit a different URL (Exim4u) to change their password. I wish they could do that within GO. As a matter of fact, I wish I could get all the features of Exim4u in GO, then I only have to deal with a single system.
Is such a thing available? I MUST only use Dovecot+Exim+MySQL so I do not want something that goes outside that set of apps.
Is such thing free or commercial?
The Zimbra hosting I'd like to replace is commercial and as such I am open to discussing this with GO developers if that is the only/best way to take.
