Mailcow Module for WHMCS Provonic

Added

Client Area — Rebuilt Interface

• Replaced the single flat details panel with a Service Actions row of composed action tiles plus a centred Mail Service Details table
• Three dedicated pages, each reached from its own action tile and from the service sidebar: Mailboxes, Aliases and DNS Records — every page can be turned off per product
• Mailboxes page: create, delete, enable/disable and re-password mailboxes, with live usage and message counts, an allowance counter and plan-limit enforcement before the request is sent
• Aliases page: create and delete aliases, including multi-destination forwarding, with per-destination address validation
• DNS Records page: the MX, A, SPF, DKIM, DMARC and autodiscover records the customer must publish, each with click-to-copy, plus one-click DKIM generation when no key exists yet
• Full Lagom support plus white/dark mode that follows the active template's own toggle, and Client Area Styling Settings that map the module's surfaces, buttons, alerts and tables onto the template's own theme variables — Lagom, Twenty-One, Six and Nexus ship with a working default mapping
• Responsive across mobile, tablet, laptop and desktop breakpoints; wide tables scroll inside their own card so the page never scrolls sideways
• Every user-facing string moved into lang/, so the interface can be translated

Service Actions — Full Lifecycle, Both Areas

• Added Suspend, Unsuspend, Terminate, Change Package, Change Password, Sync Plan Limits and Generate DKIM Key to the Service Actions row in the Admin Area and the Client Area
• In the Client Area, Suspend, Unsuspend, Terminate and Change Package each have their own product switch, all four shipping OFF and enforced server-side rather than only hidden in the interface; Sync Plan Limits and Generate DKIM Key are always available to the customer

Provisioning Modes — Own Domain Admin Or Shared Central Admin

• New per-product switch to sell sub-domains on one central Mailcow administrator you own, or (default) give every service its own mailcow domain administrator
• New per-product fields: Mailcow Panel URL, Central Admin Username and Central Admin Password (stored encrypted, never echoed back)
• Terminate is per mode: a shared service deletes only its own mailboxes, aliases and domain and detaches that one domain from the central administrator — no other customer's domain is ever touched
• Order form: for a shared-mode product the domain step offers only the free sub-domain
• Products that collect no credentials at checkout now get generated ones, written onto the service encrypted

Login — One Worker, Three Surfaces

• A real panel login from the Client Area service page, the Client Area home page and My Services listing, and the Admin Area service page, through a single-use, encrypted, expiring ticket
• A password is never posted over plain http, and an HTTP-to-HTTPS redirect no longer drops the credentials
• New product setting "Login Button Label" renames the button everywhere it appears
• Per-mailbox "Login To Mailbox" icon in the Mailboxes table (own-admin services)

Plan Limits — Enforced, And The Extras Counted

• Configurable options (Extra Mailboxes, Extra Aliases, Extra Storage) are now applied on top of the plan limits
• A plan limit can no longer fail open: adds are refused when the mail server cannot be reached
• The Add Mailbox and Add Alias buttons switch off, with the reason as their tooltip, when the allowance is used up; the server re-counts before writing

Admin Area — Rebuilt Product Configuration

• A configuration dashboard covering Mail Domain Plan Limits, DKIM & Connection, Client Area Features Visibility, Optional Client Area Pages and Client Area Styling Settings
• Domain rate limiting, Global Address List, relay domain (backup MX) and relay-all-recipients controls; DKIM key size, generate-on-creation, webmail path and a TLS-verification switch
• The service tab mirrors the Client Area overview, with Mailboxes, Aliases and DNS & DKIM popups and the full Service Actions row

New Functionality

• Change Package re-sends every plan limit and refuses a downgrade that would strand mailboxes
• Daily disk usage import from mailcow into WHMCS
• Mail domains reported to the WHMCS Server Sync tool
• Mailbox enable/disable
• Daily auto-update check

Fixed

• Every write to mailcow now verifies the response body, so a rejected provision is no longer reported as success
• POST requests keep their method and body across an HTTP-to-HTTPS redirect
• Mailbox listing uses the documented API path and is filtered to the service's own domain
• Domain creation rolls back if the domain administrator cannot be created
• Test Connection performs a real authenticated API call
• mailcow error codes are translated into readable messages; the API key is redacted in the module log
• Suspend keeps all stored mail, so unsuspending is lossless
• Per-service ownership checks on every mailbox and alias action

Removed

• The "Open mailcow Panel" custom action and the old LoginLink that only opened the login page (replaced by the real login)
