Dovecot Config Migration Validator
TL;DR
CLI + web tool for Linux sysadmins managing Dovecot mail servers that auto-detects, validates, and migrates global config files (e.g., `imapsieve_mailbox1_name` → Dovecot 2.4+ syntax) and plugin paths so they can upgrade versions without downtime or manual syntax errors
Target Audience
DevOps engineers managing email infrastructure at mid-size organizations
The Problem
Problem Context
Sysadmins upgrading Dovecot to Debian 13 or version 2.4+ face broken global configurations. Old settings no longer work, and new plugin paths must be manually added. Without the right config files, mail delivery fails, forcing admins to guess and reload services repeatedly.
Pain Points
Users waste hours searching for correct file paths, editing configs by hand, and testing changes. Plugins are ignored until paths are fixed manually. Old syntax (e.g., imapsieve_mailbox1_name) breaks without clear migration guides. Each change risks downtime during work hours.
Impact
Downtime costs revenue, and manual fixes slow down upgrades. Admins fear breaking mail delivery, so they avoid critical updates. The lack of automation turns a 10-minute task into a multi-hour headache, delaying server maintenance.
Urgency
This problem blocks upgrades and plugin updates, creating security risks. Admins cannot safely maintain their mail servers without a reliable way to migrate configs and validate plugin paths. Ignoring it risks prolonged downtime or failed mail delivery.
Target Audience
Linux sysadmins, mail server operators, and DevOps engineers managing Dovecot in production. Any team running Debian/Ubuntu servers with Dovecot 2.4+ will face this during upgrades or plugin management. Small to mid-sized businesses rely on these admins to keep email running.
Proposed AI Solution
Solution Approach
A CLI + web tool that automatically detects Dovecot config files, validates global settings, and migrates old syntax to new formats. It scans for missing plugin paths and suggests fixes. Admins run it once during upgrades or weekly to prevent drift. The tool prevents downtime by testing changes before applying them.
Key Features
- Syntax Migrator: Converts old settings (e.g.,
imapsieve_mailbox1_name) to Dovecot - 4+ format.
- Plugin Validator: Checks if plugins are in the correct paths and suggests fixes.
- Safe Testing: Applies changes in a dry-run mode first to avoid breaking mail delivery.
User Experience
Admins run the tool via CLI or web dashboard. It shows a summary of issues (e.g., "3 plugins missing, 2 old settings found"). They approve fixes, and the tool applies them. Weekly scans alert them to config drift. The web dashboard tracks history and provides migration reports for audits.
Differentiation
No existing tool handles Dovecot 2.4+ global config migration + plugin path validation. Free tools like doveconf only show current configs—they don’t fix or migrate them. This tool is the only one that prevents downtime by testing changes first and providing migration rules.
Scalability
Starts with single-server CLI use. Adds team dashboards for multi-server management. Expands with add-ons (e.g., plugin validation for new Dovecot releases). Pricing scales per server or team seat, with annual discounts for long-term users.
Expected Impact
Admins save 5+ hours per upgrade and avoid downtime. Teams can safely upgrade Dovecot without manual config guesswork. The tool becomes a must-have for mail server maintenance, reducing risk and improving productivity.
