Test an Inbound Mailbox Connection

This guide walks through Test, expected success information, and how to interpret safe IMAP/credential/TLS failure messages.

Where this fits in QC Support Ticket

Inbound email is a Max/All Access feature. Each enabled mailbox connects to an ordinary IMAP account, routes new tickets to one Department, can accept replies to existing tickets, and can process attachments and supported Agent commands according to the mailbox settings.

Inbound processing is intentionally defensive: it checks sender authority, ticket identity, deduplication, loop/bounce/automatic-message signals, attachment policy, and mailbox state before it changes ticket data.

Primary location: Joomla Administrator → Components → QC Support Ticket → Email Templates → Inbound Mailboxes.

Before you begin

  • Confirm the site currently has Max / All Access effective access before expecting the controls described here. A preserved configuration may still exist after downgrade even when the feature is locked.

How to do it

  1. Open the inbound mailbox list/edit screen and click Test for the mailbox.
  2. QCST attempts the configured IMAP/TLS/login/folder connection using the stored credentials.
  3. On success, confirm the safe connection summary matches the intended mailbox.
  4. On failure, read the sanitized error and correct host, port, encryption, certificate validation, username/password or folder details. Do not move on to parsing tests until the connection itself succeeds.

Important behavior and limits

  • Do not include IMAP passwords or full private mailbox content in screenshots/support posts; use QCST's sanitized diagnostics.

Verify the result

  • Mailbox Test succeeds before unattended processing is relied upon.
  • Process Now handles one controlled message exactly once and records a safe result without duplicate ticket/reply creation.

If it does not work as expected

  • If connection fails, verify PHP IMAP, host/port/encryption/certificate settings and credentials before changing routing.
  • If connection succeeds but processing fails, inspect sender policy, ticket reference matching, duplicate/loop checks, mailbox capabilities, and attachment policy.
