Configure IMAP Host, Port, Encryption, Certificate Validation, and Folders
This article explains the connection fields, INBOX/processed folder behavior, certificate validation, and common values without inventing provider-specific credentials.
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
- Edit the inbound mailbox.
- Enter the server's real IMAP host and port; choose the encryption mode your mail provider requires.
- Leave Validate server certificate enabled for normal trusted TLS. Disable validation only for a consciously managed test/private PKI case where you understand the security tradeoff.
- Set the Inbox folder (commonly INBOX) and Processed folder only if your mailbox workflow/provider supports the chosen move/filing behavior.
- Save and run Test. Correct host/port/TLS/certificate errors before testing ticket parsing.
Key fields and behavior
| Item | Current behavior |
|---|---|
| IMAP host / port | Mailbox server endpoint; default new mailbox port is 993 |
| Encryption | New mailbox default is SSL |
| Validate certificate | Enabled by default; keep enabled unless a controlled environment requires otherwise |
| Inbox folder | Default INBOX |
| Processed folder | Optional destination after processing |
| Capabilities | New tickets, replies, Agent commands; Internal Notes can be separately controlled |
| State | Enabled/Disabled |
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.
