// Package imapserver implements a minimal read-mostly IMAP4rev1 server backed by
// internal/mailstore, so a mail client (Thunderbird etc.) can retrieve mail this
// server received into a local mailbox. Only a single fixed "INBOX" folder is
// supported — no folder hierarchy yet (aliases/multiple folders are a later
// milestone). Login only accepts an app password (esrv_mailbox_app_passwords), never
// a mailbox's own portal password, since IMAP AUTH has no interactive MFA step.
