How to organize a mail server with a dynamic gray address?

Question

Mail server

Good day, please tell me how you can raise a mail server, for example, zimbra, in your local network, if there is only an external dynamic gray ip address - is it possible? Buying a domain without a static address, as I understand it, will not give me anything with such an address? As an option, it's just to buy a vds server and a domain and try to deploy it there, but with 20 GB you can't get around much ... What other options could there be?

Hello,
Options, for example, in a quick way:
- buy not 20 GB, but 200 GB, or how much you need there,
- take a dedicated,
- organize colocation,
- carry out statics for yourself.
