MailViewer is a GNOME application that allows users to read and decode .eml and .msg files (email files) without having to install any additional software or create an account.
It provides a graphical interface for easy navigation and rendering of email content, including attachments, HTML, and plain text.
Written in Rust with GTK4/libadwaita
- Open and view
.emlor.msgfiles: Display the email's subject, sender, receiver, and content. - Decode email attachments: View and/or save attachments.
- Support for HTML and plain text emails: Render emails in both formats (if available).
This is a flatpak/sandbox issue, you can grant it access to the host filesystem with the following command:
flatpak override --user --filesystem=host io.github.alescdb.mailviewerIf you also need access to files on a USB stick, use this command:
flatpak override --user --device=all io.github.alescdb.mailviewerAlternatively, you can install Flatseal to adjust permissions.
flatpak install --user io.github.alescdb.mailviewer
- Network : for fetching remote images (if the Show Images is checked, false by default), safe to disable if you don't wan't to see remote images.
- xdg-run/mailviewer (
/run/user/<uid>/mailviewer) : for extracting attachments and opening it with associated program. - home:rw : reading eml file and saving attachments.
