How does the tool auto-detect IMAP and SMTP server settings?

The tool queries DNS MX and SRV records and utilizes the Mozilla Autoconfig protocol database to automatically identify your incoming IMAP server, outgoing SMTP server, port numbers, and encryption protocols.

What is the MBOX format and why is it recommended for email backup?

MBOX is the universal standard format for email archiving. It allows you to import all exported messages and attachments directly into email clients like Mozilla Thunderbird, Apple Mail, and Google Workspace.

Are my email credentials or messages stored on your servers?

Never. Security and privacy are paramount: your password and email content are never logged or stored in any database. Connections are handled in-memory and terminated immediately upon download.

Why do Gmail and Outlook require an App Password?

Google and Microsoft require a dedicated App Password for IMAP access when Two-Factor Authentication (2FA) is enabled on your account, protecting your master password.

Which export formats are supported for email backup?

The tool supports MBOX (standard single-file archive), ZIP (containing individual .eml files with intact attachments), and JSON (structured metadata).

Does SmartToolKit save my email password or message content?

Absolutely not. All connections and exports are performed strictly in-memory during the active HTTP request. No credentials or email bodies are ever written to databases, logs, or server disks.

Why do I need an App Password for Gmail or Outlook?

Google and Microsoft require dedicated App Passwords for external IMAP connections when Two-Step Verification is active, preventing exposure of your primary account password.

How do I open or restore an MBOX file?

You can open and import .mbox files into free email clients like Mozilla Thunderbird (using the ImportExportTools NG plugin), Apple Mail (File → Import Mailboxes), or various webmail migrators.

Can I backup custom folders or just the Inbox?

You can backup any folder available in your account, including Sent, Archive, Drafts, and custom label folders discovered during the connection test.
