What it does
Mutt is a free terminal email client with PGP/MIME, message threading and multiple mailbox formats. Its site publishes maintained releases and documents IMAP and POP3 support.
Mutt makes sense when mail is part of a keyboard and terminal workflow. Keybindings, macros, headers and configuration can be tailored to folders or recipients. PGP/MIME support gives encrypted correspondence a place within that configurable setup.
The project publishes release and security-fix notes, so package age matters when selecting an installation. Mutt’s interface and configuration require more deliberate setup than a hosted web inbox. In exchange, the documented mailbox formats and protocol support give an experienced user control over how messages are accessed and handled.
