[Xenro] Postmark Email 1.1.0 Beta 2

[Xenro] Postmark Email connects XenForo to Postmark’s HTTPS API. Send registration confirmations, password resets and forum notifications without using SMTP ports or running a local mail server.

Postmark appears in XenForo’s standard email transport selector. Delivery settings, incoming events, email replies and setup instructions are managed from the admin control panel.

Features include:

• HTML and plain-text email, attachments, inline images and XenForo’s native email queue.
• Server API Token and transactional message stream settings.
• Request validation and a separate test-email button.
• Authenticated webhooks for delivery, hard and soft bounces, spam complaints and suppression changes.
• Native XenForo bounce and unsubscribe handling for matched recipients.
• Optional replies to watched-thread and watched-forum reply notifications, published as forum posts.
• User-group permissions, normal forum restrictions, spam checks and moderator approval for email replies.
• One-use reply addresses with configurable expiration.
• Encrypted API credentials and webhook password.
• Mail activity with automatic cleanup after 30 days.
• Built-in setup instructions.
• Preservation of existing SMTP and PHP-mail settings when switching back or removing the add-on.

Webhooks require a publicly accessible HTTPS forum. Email replies additionally require Postmark Inbound processing and an inbound address or dedicated subdomain. Replies accept plain text; attachments, automatic replies and HTML-only replies are rejected. This add-on does not provide a general mailbox.
