Fastmail.fm (a paid mail provider) also has a feature to not load remote images, and it’s on by default.
You can also set up arbitrarily complex filtering rules using Sieve, if the built-in rules UI is not sophisticated enough.
To add some more mailbox.org also has it with sieve rules. Posteo should have it too iirc
