This module provides a dedicated, parallel email stack designed to handle complex multi-account requirements, strict email routing, and robust tracking diagnostics.

Key Features:

• Multi-Account Support: Configure multiple IMAP/SMTP accounts per user.
• Strict Email Routing: Ensures business emails (Quotes, Invoices, Chatter) are strictly routed through the user's specific email account, never falling back to generic system accounts.
• Server & Account Templates: Easily deploy standardized email configurations across the company using pre-defined server templates.
• Advanced IMAP Synchronization: Robust fetching of both Inbox and Sent folders with OAuth2 support.
• Tracking & Diagnostics: Detailed email delivery tracking and "Smart Pixel" handling to avoid false-positive open rates from Google/Microsoft proxies.
• Mail Manager Actions: Exclusive server actions for Mail Managers to repair orphaned emails, re-sync attachment states, fix empty recipients, and securely delete records when necessary.
