Migrating from GroupOffice to a clean Dockerised Dovecot/Postfix stack with full data preservation is a project I can handle end to end. I'll build a Docker Compose setup with separate containers for Dovecot (IMAP/POP with SSL/TLS, quotas, and virtual user authentication), Postfix (SMTP relay with proper DKIM/SPF/DMARC), and Roundcube (webmail skinned with your logo, authenticating against Dovecot). For the GroupOffice migration, I'll extract mailboxes via IMAP sync using imapsync to preserve every message, folder structure, and flag, then migrate contacts and calendars through CardDAV/CalDAV export-import, and transfer workspace files and documents from GroupOffice's storage into the appropriate user directories. Before handoff, I'll validate data integrity by comparing mailbox counts, folder structures, and contact/calendar totals against the source. You'll get a complete Docker Compose definition, DNS configuration guide, and a step-by-step runbook covering updates, backups, and restores. I can start as soon as you share root access and GroupOffice credentials.

This looks like a great fit, I will deliver a Docker Compose stack — Dovecot, Postfix, and Roundcube in separate containers — with SSL/TLS, quota management, and your branding applied. For the GroupOffice migration, I will use imapsync for mailboxes and map contacts/calendars via CardDAV/CalDAV export to preserve folder structures and metadata intact. Questions: 1) How many mailboxes need migrating, and what is the total storage volume? 2) Are contacts and calendars stored in GroupOffice's DB directly, or exported via standard formats? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Looking forward to discussing further. Best regards, Kamran

Hi! The need to move not just emails but full assets—contacts, calendars, files, and GroupOffice workspaces—into a fresh Docker stack is the tricky part here. Most “migrations” miss the non-mail data or break calendar sync for users. A few months ago, I set up a Dockerized mail suite with Dovecot, Postfix, and Roundcube for a client needing persistent, mapped storage and seamless IMAP logins post-migration. Webmail was containerized and branded to their org. For your migration, I’ll craft a Docker Compose stack with SSL, quotas, custom webmail skin, and step-by-step docs. One thing to clarify: does every user have calendar and file data, or just a subset? This affects the export and mapping steps. I can send a short migration plan—free, before you decide. You can see similar migration work and container setups in my portfolio at work.techindika.com. — Pradeep

Howdy! I have built and migrated stacks exactly like this one, moving GroupOffice environments into clean Docker based mail infrastructure with Postfix, Dovecot, and Roundcube, so I can take this from first container definition to validated hand off without gaps. My approach is to write a Docker Compose file that isolates each service into its own container, Postfix for SMTP relay, Dovecot for IMAP and POP3 with SSL/TLS enforced and per mailbox quota configured, Roundcube in its own container authenticating directly against Dovecot over IMAP, and a shared volume layer that keeps mail storage, certificates, and configuration outside the container lifecycle so nothing is lost on restart or rebuild. I will apply your logo to the Roundcube skin, lock down authentication, and wire the fresh DNS zone with the correct MX, SPF, DKIM, and DMARC records before any live traffic touches the stack. Thank you. Marcos.

Wow! This is ideal fit for me Hello, I went through your project description and it seems like our team is a great fit for this job. I'm familiar with this kind of task and have many years of experience on System Admin, Linux, Email Handling, Docker, Dovecot, Postfix, Docker Compose Lets connect in chat so that We discuss further. Thank You

@generosoiii

Hi there, Your main risk is not just Dockerising Dovecot, but preserving every GroupOffice mailbox, folder, contact, calendar item, and workspace document without breaking daily Email Handling for users. I have spent the last 7 years solving exactly this type of Linux mail migration and System Admin handoff problem. I will build the Docker Compose stack with Dovecot, Postfix relay, SSL/TLS, quotas, authentication, and a separate Roundcube container, then migrate and verify mail, folders, contacts, calendars, and files with documented commands and restore steps. Confirm the exact GroupOffice version and export formats available for mail, contacts, calendars, and workspace files before I define the migration path. Best regards, Generoso III

Hi, I’m Md Shahid Ansari. I’ll set up a clean, Docker‑based mail stack on your Ubuntu server with Dovecot handling IMAP/POP, Postfix relaying SMTP, and a separate Roundcube container that authenticates against Dovecot and carries your logo. I’ll write a Docker‑Compose file, tune Dovecot for SSL/TLS, quotas and LDAP‑style auth, and configure Postfix for secure relay. Using my 2+ years of freelance DevOps work (e.g., the DMginie SaaS deployment with Docker, Nginx and Cloudflare) I’ll script the full migration of all GroupOffice mailboxes, contacts, calendars and attached files, preserving folder structure and searchability. A detailed runbook will document every command, backup step and restore procedure so future updates are straightforward. I’ll validate data integrity before hand‑off and keep the process transparent and secure.

@sgwtechnology

I can start immediately and build you a clean, production-ready Docker-based mail stack on Ubuntu with Postfix (SMTP), Dovecot (IMAP/POP), and a secure webmail layer (Roundcube or equivalent) fully containerized and isolated via Docker Compose. The setup will include: • Postfix configured for secure SMTP relay inside the stack • Dovecot tuned for SSL/TLS, authentication, quotas, and mailbox integrity • Roundcube webmail container with branding and secure auth against Dovecot • Persistent volumes for mail storage, indexes, and configuration • Hardened TLS (Let’s Encrypt or provided certs), SPF/DKIM/DMARC-ready structure For migration, I’ll safely transfer all GroupOffice data including: • Emails and folder hierarchy (preserving IMAP structure) • Contacts and calendars mapped into standard formats (CardDAV/CalDAV where applicable) • Files and user documents into mapped mailbox storage or linked volumes • Full validation to ensure parity before cutover Deliverables: • Docker Compose stack (fully documented and reproducible) • Migration scripts + verified import process • DNS + mail security configuration checklist • Step-by-step runbook for backup, restore, and future scaling • Post-migration verification (login tests, IMAP sync, mail flow tests) If you’re ready, I’d start with a quick audit of the current GroupOffice export structure and then move straight into the Docker architecture and migration plan today.
