Custom IMAP

​

What this integration does

Poll any IMAP mailbox for replies every few minutes — works with ProtonMail Bridge, Zoho Mail, or your own server.

​

Prerequisites

• IMAP host, port, username, password
• SSL/TLS setting for your server

​

Step-by-step connection

1. Go to Settings → Reply inbox and open the IMAP form.
2. Enter host, port, TLS, username and password.
3. Save — Runline verifies the mailbox is reachable before storing.

​

What data syncs

Pull (into Runline)

• New messages since a UID high-water cursor, matched to campaigns by threading and classified

Push (out of Runline)

• Nothing

​

Troubleshooting

• “Could not connect” → check host/port/TLS and credentials.
• Duplicate-safe: re-scans never double-ingest the same message.

​

Disconnect

Settings → Reply inbox → Disconnect inbox.
