The difference is that the alias provider or destination email provider can associate all your accounts with your identity. I do not want to give this ability to either the alias provider or the email provider. It is a different threat model. (Please correct if I am wrong)
I did not say how many different accounts I have, but you can assume my separation of accounts is sufficient for my needs.
I should clarify that I already have multiple email accounts, so extra aliasing is not necessary. I'm looking for an email client application I can run on my desktop which separates the accounts well enough from the email provider.
Yes. I think what I wanted to say is you can set up Tor PoW for an onion in addition to currently using Cloudflare for clearnet, but sounds like that will be part of the server migration rather than happening now. Thanks for the response.
Tor introduced native DDoS protection for onion services using a transparent Proof-of-Work defense over a year ago: https://blog.torproject.org/introducing-proof-of-work-defense-for-onion-services/
You should strongly consider making the switch and turning on this feature. I was very surprised to find that this instance was being Cloudflare blocked. Maybe we could help with funding if needed.
I'm having a hard time finding how to access about:profiles, but in looking for this I found you can disable the "download messages on startup" option. Maybe Thunderbird is the solution. It will require some more investigation, but this is giving me hope.
