Hosting mailman for another domain


New Member
Hi, I'd like some advice on how to handle the following situation.

A customer with an account on an Windows server elsewhere (too hard to move) wants to make use of mailman for a small list of members (volunteer club) and wonder if I can host this mailing list for them under their domain. (Not under my or another domain).

I assume they create an mx record to point to my VPS IP address and I create an MX entry for But I'd also need a Cpanel account for them to create and manage this mailing list.

Is it possible? How do I go about it? Do they simply access their Cpanel account using the IP address? If so do I need a dedicated IP or can they use vps-ip/accountname?

Would it better if they create a subdomain at their registrar such as and I create that account they can point to?

Sorry for all the questions but I can't quite grasp the best way to deal with this.

Thanks in advance
