VM is a mail reader that runs inside GNU Emacs, a once popular mail client brought back to life as a community project. VM 9.0.0 is the first major release since the revival, with many bug fixes and new features.

VM features:

- Non-blocking IMAP and POP access, so you can fetch and save mail while carrying on in Emacs. - IMAP and POP mailboxes cached on disk, so a folder stays accessible when the server is unreachable. - Virtual folders: a folder view of messages across multiple folders, chosen by selection criteria. - MIME support with inline and external display. - HTML mail displays on a stock Emacs, through shr - Folders in plain mbox format, and mboxcl2, which does not irreversibly quote lines starting with "From ". - PGP access with EasyPG, Emacs's standard gpg interface. - Emacs 28.1 or later. - Extensive documentation.

and much more

To install from NonGNU ELPA:

  M-x package-install RET vm RET
