Delta chat through tor?

email account is anonymous

If you register an email account through tor, I would expect it to be
an anonymous email address.

does not support routing through TOR

Meaning there are no settings in delta chat to set socket ports?

might be able to configure your networking to use TOR for Delta Chat’s network connections

That could be proxychains?

The center of my question is, if delta chat’s data transfers are relayed through
tor, then the delta chat program itself does not display data which
will compromise the anonymity which tor provides?

On a broader level it is about who can benefit from utilizing delta chat? If
delta chat in a few steps would be able to do anonymous encrypted
end 2 end communication, delta chat would get an option for journalists and
activists.
What I suggest is not building tor into delta chat. Adding socket proxy
settings to delta chat could be an option. Following instructions people
could then install tor on their computer, admittedly not a simple task
for everyone, and set the tor ports in delta chat’s socket proxy
settings.
