Now, my idea is to set up an NFS volume on the NAS, and configure the cloud-based server as the client. I would like to store only the most recent emails on the main server, and keep the whole data set on the NAS.
Doing NFS over the Internet is such a bad idea. Don't do it.
Also don't do NFS over a WAN link inside a VPN. The latency will kill you.
In addition to that, the flakiness of the on-prem NAS will hard-lock any process accessing or trying to access anything on the NFS share during times where it is not available.
This setup would severely degrade not only the performance but also the availability of your mails.
Do not do this.
In your case I only see the option to either deal with the increased costs, move to a different ISP which is cheaper or move to a hosted mail solution, which may also be cheaper.
But jerry-rigging an NFS share on a flaky box over a WAN link is such a bad idea. Please, reconsider.
