Your Email Provider Doesn't Matter. Your Invoices Do.
Connect any IMAP-compatible mailbox — Yahoo, Zoho, Fastmail, ProtonMail Bridge, iCloud Mail, or a self-hosted corporate server — and extract invoices through the same AI pipeline as Gmail and Outlook users. encrypted credentials, targeted folder selection, and configurable host/port/TLS for any mail server.
Key IMAP Invoice Scanner Capabilities
Built-in functionality that eliminates repetitive document tasks
Broad Provider Compatibility
Works with Yahoo, Zoho, Fastmail, ProtonMail (Bridge), iCloud Mail, AOL, GMX, and virtually any corporate server that exposes an IMAP endpoint — Zimbra, Dovecot, Postfix, and more.
Credentials Encrypted at Rest
IMAP username and password are kept encrypted before storage. Decryption occurs only on the server during active sync operations — credentials are never returned to the client.
Targeted Folder Selection
Scan the entire mailbox or specify individual IMAP folders — Inbox, Invoices, Finance — to reduce noise and focus processing credits on high-value directories.
Same AI Pipeline as Gmail & Outlook
IMAP-sourced documents pass through the identical extraction engine as Gmail and Outlook: 15-field structured output with per-field confidence scoring and the same pre-classification filtering.
Configurable Host, Port & TLS
Specify custom IMAP hostname, port number, and TLS/SSL mode for self-hosted or on-premises mail servers. Full control over the connection handshake.
Automatic Background Sync
Set a sync schedule and let Inbox Ledger check for new emails periodically. Each run fetches only messages received since the last cursor — no full rescans.
Document Types Extracted via IMAP
AI identifies and extracts data from every supported format
Vendor Invoices — Any Provider
Whether your mailbox runs on Yahoo, Zoho, Fastmail, or a self-hosted Dovecot server, every invoice attachment is discovered and processed identically.
Regional Provider Invoices
Invoices arriving on regional services like GMX (Germany), Yandex.com (international), or Naver Mail (Korea) are supported through standard IMAP.
On-Premises Mail Server Invoices
Connect to Exchange (IMAP-enabled), Zimbra, Postfix/Dovecot, or any corporate mail infrastructure to capture vendor invoices automatically.
Automated Billing Attachments
Recurring invoices from hosting providers, payment processors, and SaaS platforms that deliver PDF attachments on a schedule.
Tax & Government Notices
VAT invoices, tax authority notices, and government-issued financial documents delivered as PDF attachments to your IMAP mailbox.
Folder-Organized Archives
Point the scanner at specific IMAP folders — "Invoices," "Finance," or "Vendors" — for targeted extraction with minimal noise.
How It Works
From connection to first extracted invoice in under five minutes
Enter Connection Details
Provide your email address, IMAP hostname, port, and password. Credentials are kept encrypted before storage — they never exist in plaintext.
Choose Target Folders
Select which IMAP folders to scan: the entire mailbox, the Inbox only, or specific folders like "Invoices" or "Finance." Narrow the scope to save credits and reduce noise.
AI Classifies and Extracts
The scanner retrieves attachments from your selected folders, pre-classifies each one, and routes financial documents through the extraction engine — 15 structured fields per document.
Unified Dashboard Access
Extracted invoices appear alongside data from Gmail, Outlook, and manual uploads. Filter, tag, and export from a single view.
Who Benefits Most
Designed for finance professionals and teams managing high-volume documents
Companies on Non-Google/Microsoft Email
Businesses running Zoho, Fastmail, or hosting-provider mailboxes get the same AI extraction pipeline and structured output that Gmail and Outlook users rely on.
Multi-Client Accounting Firms
Connect IMAP mailboxes from clients on diverse email providers — all managed from one Inbox Ledger organization with isolated data and independent sync states.
Privacy-Focused Professionals
Consultants and freelancers using Fastmail, Tutanota, or iCloud Mail can scan for invoices without changing providers or granting OAuth access to a third party.

Frequently Asked Questions
Any provider supporting the IMAP protocol — Yahoo Mail, Zoho Mail, Fastmail, ProtonMail (via Bridge), iCloud Mail, AOL, GMX, and virtually any corporate server running Exchange (IMAP-enabled), Zimbra, or Dovecot.
Your IMAP username and password are kept encrypted before being persisted. They are decrypted only on the server during active sync and are never returned to the browser or included in API responses.
Yes. Specify a custom IMAP hostname, port number, and TLS/SSL mode during setup. This works with any self-hosted, co-located, or on-premises server that exposes an IMAP endpoint.
The Gmail and Outlook scanners use native APIs (Gmail API, Microsoft Graph) for faster incremental sync and richer metadata. Use the IMAP scanner for any provider that lacks a dedicated connector — it delivers identical extraction accuracy.
Yes. During setup you select which IMAP folders to include. If you route invoice emails to a dedicated folder, scanning only that folder reduces processing time, credit usage, and noise.
IMAP does not natively support 2FA. Providers that enforce 2FA typically offer app-specific passwords for IMAP clients. Use the app-specific password when connecting to Inbox Ledger.
You configure the sync interval or trigger a manual sync at any time. The scanner maintains a per-source cursor, so each run processes only messages received since the previous checkpoint.
