Mail-Client Pinephone

Does anyone know an IMAP mail client that works well on the Pinephone?
Everything I have tested so far is not optimized for a mobile view.

I am looking for the same, or info where I can get started setting these to use the pinephones screen resolution. All I need to start using this as a daily test driver is a working mail client.

Best option is probably Geary, right now…
