Understand QCST Max Inbound Email Ticket Handling
This article explains how Max mailboxes create tickets from ordinary email, add authorized replies, protect attachments, use one department per mailbox, and avoid plus-addressing dependence.
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.
- Confirm Joomla Mail works before diagnosing QCST template delivery. For inbound mail, confirm PHP IMAP is available and keep one controlled test message available.
Inbound model
- One configured ordinary IMAP mailbox can create new tickets and/or append authorized replies.
- Each mailbox has one Department context plus default Category/Priority for new ticket routing.
- QCST recognizes existing-ticket replies from ticket identification plus authorized sender checks; it does not depend on plus-addressing aliases.
- Inbound attachments are revalidated and stored as protected ticket attachments.
- Deduplication and automatic/bounce/loop filtering prevent obvious mail loops and repeated message import.
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.
