Dovecot jobs
I’m planning a full move of a 29-year-old custom hosting platform over to a fresh VPS reseller account and I need a seasoned Linux infrastructure engineer to handle every step of the transition. The current stack spans CentOS 6 and 7 with Apache web services, Sendmail + Dovecot mail delivery, BIND-named for DNS, Mailman mailing lists, DKIM/SPF records, MX routing, virtusertable aliases, and a range of hand-tuned legacy scripts that keep it all working together. The web, mail, and DNS layers (Apache, Sendmail, Dovecot) all carry bespoke configuration tweaks that must be kept intact. I have detailed documentation for these customisations, including conf file excerpts, directory layouts, and notes on historical work-arounds, so you will not be reverse-engineering them fro...
My production web and email services have been offline since I tweaked a few configuration files on a Centos box. I need a seasoned sysadmin who can jump in over SSH, diagnose why both the web stack and the mail stack refuse to start, roll back or fix the mis-configuration, and return everything to stable operation. Here ...postfix mail flow so IMAP/SMTP works and queued messages deliver • Harden the server once it is up so the same outage cannot reoccur • Provide a brief summary of the root cause and the exact files you adjusted Acceptance is simple: the website must load publicly, and test emails must send, receive, and authenticate without errors. If you are confident with Linux recovery, DNS, Postfix or Exim, Dovecot, firewalls, and SSL, I’m ready to give y...
... Docker-based email server running on Ubuntu with Dovecot handling IMAP/POP and SMTP relayed through Postfix inside the same stack. The instance must include reliable webmail access—Roundcube or similar is fine as long as it sits in its own container and authenticates against Dovecot. My current platform is GroupOffice. I want every mailbox asset moved across, including messages, folder structures, contacts, calendar items, and the associated files/documents stored in user workspaces. When the job is complete users should log in through the web interface or their usual mail clients and find all historical data intact and searchable. Key deliverables: • Docker Compose (or equivalent) definition with all containers configured • Dovecot fully tune...
...org sends and receives fine through the built-in webmail, yet any external IMAP client—specifically Spark and EspoCRM—throws a straight connection failure when set to SSL/TLS. I’ll give you both SSH and Webuzo panel access. The test mailbox is • Username: test @ • IMAP host: • Password: test1234qwerty Your job is to log in, inspect my Webuzo mail stack (Dovecot, Exim, certificates, ports, firewalld, etc.), identify what’s blocking the SSL/TLS handshake, and apply the fix. When you’re done I need: 1. Spark and EspoCRM connecting normally over SSL/TLS on the standard secure ports. 2. A short note outlining what you changed so I can replicate it on future domains. That’s it—once both clients sync without erro...
...performance and control. The work involves three connected tasks: 1. Domain – Transfer the domain and application out of GoDaddy to EC2, set it up in Route 53, and make sure DNS records propagate smoothly with no noticeable downtime. 2. Email – I’d like mail to live on AWS as well using SES or WorkMail I want it running on an EC2 instance. This means provisioning and hardening the server (Postfix/Dovecot or similar), configuring SPF, DKIM, and DMARC, and confirming that send/receive works without landing in spam. Deliverables • Website live on AWS and reachable through the current domain • Domain fully managed in Route 53 • EC2-based mail server sending and receiving with SPF/DKIM/DMARC passing • Short hand-over guide covering insta...
...can reliably send and receive email. Security is paramount, so the build must include SMTP AUTH, TLS/SSL, and STARTTLS throughout. Mailboxes will be accessed over IMAP only; no POP3 is required. Here is what I expect: • Install and configure Postfix on a Linux host of my choosing. • Enable and verify SMTP AUTH, TLS/SSL, and STARTTLS for all connections. • Integrate an IMAP service (such as Dovecot) and align it with the Postfix user database. • Harden the server with sensible defaults—SPF, DKIM, basic rate-limiting, and anti-relay measures. • Provide concise documentation that shows key config files, how to add new domains/users, and how to back up the settings. I’ll supply root or sudo access to a fresh VPS and DNS records as needed...
I need a single, reliable inbox set up on my existing DigitalOcean droplet so that our clients can start writing to us directly. The domain is already live and pointing to the droplet; all that’s missing is a properly configured mail stack. I’m flexible on the underlying software—Postfix, Exim, Dovecot, or a sensible combination—so feel free to propose the stack you’re most comfortable hardening and supporting. Security (TLS), clean DNS records (MX, SPF, DKIM, DMARC) and straightforward logging are critical, but the overall footprint should stay light since we only require one mailbox for now. Deliverables • Install and configure the chosen mail server stack on the droplet • Update DNS to route mail through the new inbox with validated S...
I need a str...inboxes as I like under my own domain, strictly for internal company use. I will be creating each mailbox myself, so the focus is on providing the underlying configuration and a clean Roundcube webmail interface where every new account automatically has its own secure password and can both send and receive without issues. Here’s what I expect: • Install and configure the mail stack (Postfix/Dovecot or comparable) on my VPS or cPanel server so it supports unlimited mailboxes on the domain. • Deploy Roundcube, theme it lightly with my logo, and make sure each mailbox can log in independently via HTTPS. • Set DNS (MX, SPF, DKIM, DMARC) for solid deliverability. • Document, step-by-step, how I can manually add or delete accounts and rese...
...must comfortably run anything from plain HTML to PHP-driven WordPress and full e-commerce builds, so current versions of Apache or Nginx, multiple PHP versions, and MariaDB/MySQL are expected. Email has to be part of the same box. I am leaning toward a Roundcube or Cosmos webmail front-end, but I am open to a better suggestion if you can justify it. Under the hood, please wire up a solid Postfix/Dovecot combination with SPF, DKIM, and DMARC so outgoing mail lands in the inbox and not spam. Deliverables • Latest LTS Ubuntu installed, updated, and secured (UFW and basic hardening) • Webmin/Virtualmin configured over HTTPS, ready for virtual-host creation • Web stack (Apache or Nginx, PHP-FPM, MariaDB/MySQL) tuned for performance • Let’s Encrypt S...
All messages viewed through Roundcube are loading as completely blank for every mailbox on the server. This started right after I adjusted a few WHM /- cPanel settings, so I’m sure something I changed triggered the problem. I need someone to trace the root cause inside WHM, cPanel and Roundcube—whether it’s a dovecot/IMAP hiccup, missing MIME handlers, cache corruption, or a permissions mix-up—and restore normal message display without losing any data. Deliverables • Diagnosis summary explaining what went wrong • Configuration changes or patches applied (with exact file paths or WHM panels noted) • Confirmation that emails now render correctly in Roundcube for multiple test accounts Please be ready to work directly on the live se...
I have a freshly-provisioned VPS that needs to handle all of my domain’s email. The core job is to turn this blank server into a fully functioning mail system that can send and receive reliably while passing modern deliverability checks. Here’s what I need done: • Install and configure the mail transfer and delivery stack on the VPS (Postfix/Dovecot or an equivalent, as long as it is stable and well-documented). • Enable secure access over SMTP, IMAP and POP3 with valid TLS certificates. • Create the first mailboxes and aliases, confirm they work from common clients such as Outlook, Gmail (via external POP/IMAP), and Thunderbird. • Set up DNS records—SPF, DKIM, DMARC and the appropriate A/MX entries—so that test messages land in ...

You’ll be expected to arrive on-site, review the existing Ubuntu environment, adjust any misconfigurations, migrate data and user accounts cleanly, then validate that everything functions exactly as before—or better—once the cut-over is done. Solid knowledge of Ubuntu server administration, Postfix/Dovecot, DNS, SSL/TLS and mail security best practices will be essential to get this wrapped up quickly. If you’re available to start immediately in New Delhi and can demonstrate hands-on experience with Mobodoa at t...
I have a VPS already provisioned with Ubuntu and I simply need cPanel/WHM installed and activated on it...activated on it—no extra hardening or performance tweaks are required beyond what the vanilla installer provides. A straightforward, clean setup that leaves me with a working cPanel login, the default nameserver configuration, and the ability to add domains right away is all I’m after. Please be comfortable running the official installation script, verifying basic services (Apache/Nginx, Exim, Dovecot, MySQL/MariaDB, etc.) start correctly, and confirming I can reach WHM over the browser once you’re finished. SSH root access is ready for you as soon as we agree on a time. See details of the cPanel to be installed below:
...editions. It must be the Community/Open-Source edition only. Scope of Work & Technical Requirements: 1. Infrastructure & OS: o Deploy on on-premises Linux infrastructure (e.g., Ubuntu LTS). o Optimize OS kernel and file systems for high I/O performance (2000+ concurrent users). 2. Software Stack (Strict FOSS Policy): o Must use a fully open-source stack (e.g., Mailcow, SOGo, or a custom Postfix/Dovecot stack). 3. Outlook Compatibility (The Critical Requirement): o Must implement Open Source ActiveSync (e.g., via SOGo, Z-Push, or Grommunio Community) to ensure two-way sync. o Outlook: Users must be able to use Outlook (Desktop) to sync Email, Calendar, and Contacts without purchasing third-party plugins. 4. Webmail & Collaboration: o Deploy a modern, open-source Webmai...
...reinstall Postfix. Since then, messages are bounced or never show up because the two core services are tripping over file-system restrictions: • Dovecot is throwing file and folder permission errors whenever it tries to reach users’ maildirs. • Postfix will no longer accept incoming mail, clearly a permission-related failure. I need a clean overhaul of user, group and directory rights so that both services can coexist again without rejecting or losing mail. The job is finished when: 1. Dovecot reads and writes every mailbox without permission warnings in the logs. 2. Postfix reliably receives external messages and hands them off to Dovecot. 3. Test messages in and out complete successfully, with logs free of permission or authentication erro...
My current mail stack runs on FreeBSD with Dovecot and holds somewhere between 50 GB and 200 GB of data across fewer than ten mailboxes. I already maintain an active Microsoft 365 tenant and the target mailboxes are provisioned, so this engagement is strictly about the migration itself—no account creation or licence work is required. Scope • Plan and execute a clean IMAP-based transfer (IMAPSync, MigrationWiz, or a proven equivalent is fine). • Carry out one or more delta syncs to capture messages that arrive during the cut-over window. • Coordinate DNS MX switch-over so downtime stays near-zero. • Validate that each user’s folder structure, flags, and any server-side filters arrive intact. • Provide me with a brief post-migration repo...

...review and fix issues on our Plesk server running on Debian 11. The system is operational, but several components – especially the mail services (Dovecot/Postfix) – are not working properly after recent issues. In the background, a Proxmox Mail Gateway (PMG) is running as a separate filtering and relay system. The mail flow is configured as PMG → Plesk → Mailboxes. There is also an API integration or automated script that adds domains from Plesk directly into PMG for mail relay and filtering. It is possible that part of the current issue is related to this integration. Current issues: Plesk Webmail (Roundcube) not accessible or showing errors Dovecot not starting properly / SSL configuration errors Incoming emails from specific domains being reject...
I’m looking for a seasoned Linux admin who can take full ownership of a production-grade server that currently runs Postfix + Dovecot for email, a web server delivering both static and dynamic content, a MySQL datastore, and three core backend services (API, authentication, and data-processing layers) that feed our mobile app. Your mission is to keep everything fast, secure, and highly available. Day to day you’ll be hardening Postfix/Dovecot, tightening firewall rules, troubleshooting the occasional delivery hiccup, and fine-tuning VHosts so the web layer stays responsive while we push new releases. On the backend side I’ll rely on you to monitor resource usage, roll out updates with minimal downtime, and make sure each service talks to MySQL efficiently...

I need you to install and harden a custom IMAP / SMTP stack, establish secure TLS connections, set up spam-/virus-filtering, and then migrate every mailbox, alias and folder from the current server with zero data loss or noticeable downtime for users. Customisation is important: Postfix-Dovecot is my first thought, but I’m open to Exim or Sendmail if you can justify the choice and keep management straightforward. Whichever route you pick, please document all configs so I can maintain the system later. Deliverables • Fully functional Linux mail server running chosen IMAP / SMTP software • All user data, folders and aliases copied from the old host and v...
I have a fresh VPS at OVH that’s running AlmaLinux 9 and has whm/cpanel license. I need it fully prepared with cPanel/WHM and then want all my existing assets moved over smoothly.
