nexmail is a self-hosted email client in the browser. It brings several IMAP mailboxes together in one window: iCloud, Google, Microsoft or any other provider. One container, a single SQLite file, no second database and no cloud service that gets to see your mail.
It reads, writes, searches, labels, schedules and sends, keeps a calendar over CalDAV, syncs address books over CardDAV and can reach you with the browser closed. Every member of the household gets their own account and mailboxes. The interface is available in English and German.
nexmail is a mail client, not a mail server. Your mail stays with your provider.

nexmail is a self-hosted email client in the browser. It brings several IMAP mailboxes together in one window, with a merged view of all inboxes, full-text search, labels stored as IMAP keywords, rules, signatures, scheduled sending with undo, a calendar over CalDAV, address books over CardDAV and push notifications.
On first start you create the first account in the browser. Until that account exists anyone who can reach the page can create it, so do this before you expose nexmail beyond your home network.
All data lives under /data: the SQLite database, attachments, and the key that encrypts your stored mailbox passwords. Back up that one folder. Keep it on a local disk, never on an SMB or NFS share, because SQLite locking is not reliable over network filesystems.
Set PUID and PGID to the user that should own the files. 99 and 100 are the Unraid defaults and work out of the box.
