I've been thinking of migrating our mail infrastructure to a virtual server, running in the Web3 IPFS cloud - without having a physical IP address attached to it.
As others have indicated, an IP address is required to receive email via SMTP. It's possible that the IP address isn't on the mail server but instead some sort of gateway system. But the world sending email to / receiving email from your ""server will require an IP address.
The obvious question becomes: How do I publish an address to it? How do I set up an MX record to point to a socket listener that has nothing but an IPFS CID to identify it? I can set up a DNS_Link TXT record, pointing to an IPNS record - but MX records have to resolve to an FQDN.
You don't. SMTP requires an IP.
Any thoughts? Any thoughts on where to ask the question?
You may be able to stand up a VPS that has (access to) an IP address to speak SMTP out to the world and IPFS out the back for storage. You may even be able to have multiple such VPSs sharing the same IPFS, including running client access services IMAPS, POP3S, etc.
But I'm quite certain that SMTP with the world won't work without an IP address somewhere.
