IMAP Mailbox Browser
Connect to an IMAP mailbox — browse folders and read recent messages straight from your browser.
Overview
A web-based IMAP client for reading email. Point it at any IMAP server (Gmail, Outlook/Office 365, Fastmail, your own Dovecot) with host, port, TLS mode and credentials, then browse the mailbox's folders and read the most recent messages — sender, subject, date and the message body. Perfect for testing IMAP credentials and TLS settings or quickly checking what landed in a folder. The receive-side companion to the SMTP Email Sender. Signed in, you can reach private / LAN / localhost servers and save mailboxes that sync across devices — the password is encrypted at rest with AES-GCM. Signed out, the connection is one-time, public-host only, and never stored.
