mutt

text-based mailreader supporting MIME, GPG, PGP and threading

Not tested on a device yet. What that means

mutt in Breadstick

Breadstick runs Debian's own mutt package for ARM64, the build a Debian 13 computer with an ARM processor installs, so mutt should look and behave as it does on a Linux PC. It is an interactive program that runs inside a terminal rather than in a window of its own: in Breadstick's Terminal, or in any terminal window on the Linux desktop, and it needs no Desktop or Floating session running.

Commands in the package

mutt
mutt_dotlock
smime_keys

Type one in Breadstick's Terminal to run it.

Terminal mail and chat programs run inside Breadstick's Terminal and use Android's own network connection, a VPN connected in Android included. More in the docs: The Terminal.
