...Review the existing rule set, then create a clean group of rules that closes unnecessary ports while keeping web, SSH and mail services functional. • Tidy up filter policies that tie into the DNS Resolver, add the correct DNS reflection settings for internal hosts, and be sure split-DNS look-ups resolve exactly the same from inside and outside the network. • Re-establish outbound mail on Poste (postfix/SMTP 587) and verify IMAP/POP login is restored. Right now we can receive mail but cannot send, and the web-login is disconnected. • Publish and propagate the proper MX records so external lookups stop failing with the “No MX records found” error. The job is complete when: 1. pfSense passes traffic only on the intended ports and DNS queries resolve...

My Linux mail server sends messages straight to the spam folder even though the IP is clean and SPF, DKIM, and DMARC are already configured. I occasionally see brief service outages as well. I’m looking for an email specialist who can quickly review my current setup, pinpoint what Gmail, Outlook, and other providers still dislike, and get messages landing in the inbox. Key tasks • Audit the Postfix/Exim configuration and DNS records to verify rDNS, HELO, header alignment, and TLS settings. • Spot content or list-quality factors that might trigger spam filters. • Apply fast, low-impact fixes where possible and give me a concise checklist for any larger changes. • Run live tests to confirm inbox placement and stability across major providers. Deliv...

We are looking for an experienced Linux/Plesk administrator to 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 erro...

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...

...(recipient, subject, message) is already structured and ready to go. Important: I need pre-warmed domains and IPs ready for immediate use! Requirements – Provide SMTP access or a REST API for integration – Infrastructure must be self-hosted and independent from third-party platforms – Pre-warmed IPs/domains required for high deliverability from day one – Experience with mail server setups (e.g., Postfix, Mailcow, Mailu, Exim) – Expertise in: • SPF, DKIM, DMARC, header optimization • Domain/IP warm-up processes • Bounce handling, feedback loops • Spam filter avoidance and blacklist prevention – Optional: Use of multiple sender domains/IPs for load balancing Dashboard & Monitoring I require a web-based dashboard with the...

...cost and effort. Text generated by FL: I have a fresh Linux server ready to become our new dedicated mail host. 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 h...

I have a fresh Ubuntu server that needs to be production-ready. Here’s what I’m looking for: • Install & configure the core stack – whether that ends up being Apache or Nginx for the web layer, MySQL/PostgreSQL for the database, or Postfix/Exim for email, I want clean, reproducible installs with sensible defaults. • Lock the machine down: set up a firewall (UFW or iptables), issue and force SSL/TLS certificates (Let’s Encrypt is fine), and create granular user-access controls with key-based authentication and sudo rules. • Optimise and monitor performance: tune kernel parameters, configure caching where appropriate, and deploy lightweight monitoring (e.g., Netdata, Prometheus node exporter) so I can keep an eye on CPU, RA...

Server Configuration & Security Hardening Objective: Deploy a secure mail server environment with proper authentication, reputation safeguards, and inbound spam filtering to ensure outgoing emails are trusted and incoming spam/malware is blocked. Scope of Work 1. Outgoing Email Configuration – Deliverability & Reputation Install and configure a Mail Transfer Agent (MTA) (e.g., Postfix, Exim). Set up and validate: SPF (Sender Policy Framework) DKIM (DomainKeys Identified Mail) DMARC (Domain-based Message Authentication, Reporting, and Conformance) Configure rDNS (reverse DNS) for the server IP. Implement HELO/EHLO hostname matching. Enable rate limiting and outbound spam protection (e.g., Postscreen, RBL checks). Set proper envelope sender policies and bounce ...

I need a full-stack developer (Laravel or WordPress) with Docker and Linux server experience. The project is – “Tu espacio en red”, a subscription-based platform that gives users: A Nextcloud account (different disk quotas, apps, and permissions by plan). A Mail account on our own mail stack (Postfix + Dovecot + Rspamd + OpenDKIM + OpenDMARC + Roundcube). Everything hosted in one Docker environment on a single dedicated server. The base server is ready — I just need the full system working, including design and branding customization. Main tasks Platform (Laravel or WordPress) User registration & login system. Admin dashboard to create/edit plans/packages (disk quota, mail quota, Nextcloud apps). Subscription system (Stripe or PayPal). Automatic provisio...

I need a complete, production-ready mail system installed in a physically secure datacenter environment. The core requirement is end-to-end delivery over SSL/TLS so every connection—IMAP/POP, SMTP submission, and server-to-server relay—remains encrypted by default. I haven’t locked myself into a specific stack, so feel free to propose Postfix with Dovecot, or any other combination you trust; stability, security, and maintainability are what matter most. • Mail services – Install and configure the chosen SMTP and IMAP/POP services. – Generate or obtain trusted SSL certificates (Let’s Encrypt is fine) and enforce TLS-only connections. • DNS & delivery hygiene – Create the required MX and A records. – Advis...

...application serving approximately 50,000 users. The system will be hosted on a single Azure Virtual Machine, using Node.js (Express) and PostgreSQL. The API handles a workload that is over 99% read-heavy with lightweight queries and minimal writes, leveraging client-side caching to minimize server load. Email alerts will be configured using a server-side email solution (e.g., a local SMTP server like Postfix) provided on the Azure VM. The Chrome Extension enables partner developers to mouse-over, highlight, and select DOM elements to generate selectors dynamically. The same developer will build both components to ensure seamless integration and testing. The winning bidder will receive detailed specifications, including PostgreSQL schemas, tables, and example data. Scope of Work ...

I need a reliable SMTP server configured from scratch so my custom-built HTML/CSS website can send time-sensitive transactional emails—order confirmations, password resets, notifications—without delay or spam issues. Here is what I expect: • Provision and harden the SMTP service (Postfix, Exim or another Linux-friendly MTA) on my VPS or cloud instance, enabling TLS, rate-limiting, and authentication. • Configure DNS records—SPF, DKIM and DMARC—for the primary sending domain. • Set up SMTP AUTH so my web application can connect securely from server-side scripts. • Run deliverability tests (Mail-Tester or similar) and share the results so I can see we’re landing in the inbox. • Supply concise setup documentation: host...

I manage several websites on a dedicated server running Plesk, and right now outgoing mail is simply not being delivered. I already relay through a smart host, yet messages either vanish or end up flagged as spam. I need the full mail stack—Postfix/Qmail, SMTP authentication, SPF, DKIM, DMARC, reverse DNS and relay settings—reviewed and corrected so every domain on the server lands reliably in recipients’ inboxes. Here’s what I expect: first, a quick audit of the current configuration and DNS. Next, the necessary changes to Plesk and the smart-host settings to eliminate delivery issues. Finally, clear documentation of what was changed so I can maintain it. Acceptance criteria • All domains pass SPF, DKIM and DMARC checks on MXToolbox (or similar) &...

The collaboration starts with a single day’s send; if the metrics are strong, we’ll...

I want to spin up my own SMTP server—nothing outsourced—so I can control deliverability, logs, and security end-to-end. The instance must require authentication before mail is accepted. I’m open on the exact method (username-password, OAuth, or an IP-based rule set); propose what you think fits best for a secure yet straightfo...DMARC) so messages land in inboxes instead of spam. Once everything is live, please send test messages from and to multiple providers (Gmail, Outlook, Yahoo) and supply the logs showing successful delivery. Finally, give me concise step-by-step notes so I can manage users and rotate credentials on my own later. If this is in your wheelhouse, let me know which MTA and associated tools you’d use—Postfix, Exim, or something else&m...

I’m putting together a production-grade SMTP relay that any of our application servers can use without storing or passing passwords. Instead, the relay must recognise and trust specific IP addresses we provide and reject everyone else, so there’s no chance of it turning into an open relay. Core requirements • Postfix is the front-runner, but I’m open to another MTA if you feel it better suits the brief. • The underlying OS hasn’t been chosen yet (Ubuntu, Debian or CentOS are all on the table), so factor in a clean, reproducible install. • TLS must be enforced for all outbound traffic. • Each message should allow a custom “From” name and address. • Once I register the domain, I need full SPF, DKIM and DMARC align...

I manage an application that relies on a self-hosted SMTP server, and lately I’ve been battling low delivery rates and a frustrating spike in hard bounces. My goal is to squeeze every bit of performance out of the existing in...tweaks or architectural recommendations—whether that means smarter queue management, improved list hygiene automation, or, if evidence suggests, partial migration to a third-party relay or hybrid setup. • Clear documentation of all changes plus a short checklist I can rerun to keep the system healthy. I’m open to proven best practices and any monitoring or warm-up tools you normally trust (Postfix tools, PowerMTA, Mailgun analytics, etc.). Once complete, the system should show measurable gains in throughput, far fewer bounces, and ov...

I’m running Ubuntu 24.04 with Virtualmin Pro, Apache and Mailwizz. Every domain on the server already has its own dedicated IP, but the one-to-one mapping isn’t working where it matters: Mailw...every address, confirm STARTTLS works, and eliminate the OpenSSL/TLSv1 complaint. • Leave the existing Virtualmin/Apache stack intact; this is purely a mail and networking fix. • Hand me a brief rundown of what you changed so I can repeat it if I add new domains later. I have already walked through the obvious firewall rules and a few Postfix tweaks without success, so I’m looking for someone who has concrete experience wrangling Virtualmin, Postfix, Dovecot and Mailwizz at scale. If you’ve untangled similar 587 or TLS issues before, that’s...

... Outlook throws intermittent authentication and connection errors, while webmail gives no useful clue—sometimes a cryptic 550, other times nothing at all. Multiple mailboxes are affected and the situation is critical for daily business. I need someone who knows Plesk mail inside out to jump in right now, track down the root cause, and leave the system rock-solid. That means digging through Postfix (or Qmail, if that’s what you find), checking queues, log files, SPF / DKIM / DMARC records, SMTP and IMAP settings, DNS alignment and any Outlook-side tweaks until everything behaves normally and deliverability improves. Deliverables—what I will accept as “fixed”: • Every affected account can reliably send and receive to major providers (Gmail...

...own VPS with cPanel and need someone to configure everything so my marketing emails actually reach inboxes instead of spam. The plan is to send directly from the server—no MailChimp or other third-party platforms—so the SMTP service on the box must be tuned, authenticated, and fully tested. You’ll connect, set up and verify SMTP on my domain, handle SPF, DKIM and DMARC records, adjust Exim (or Postfix if that’s what you prefer), and make sure rDNS/PTR matches. Once done, a quick deliverability test (Mail-Tester or similar) should show a clean score and my first small batch of marketing messages should send without errors. Deliverables • Correctly configured SMTP on my VPS/cPanel account • Updated DNS with working SPF, DKIM, DMARC and matchi...

...straightforward portal added to that lets visitors instantly create their own @ mailbox. The flow is simple: a visitor picks any available username, sets a password, and the system provisions the address in real-time. No social logins or multi-factor steps—just classic username-and-password authentication. Behind the scenes, the portal must talk to my mail server (cPanel, Postfix, or an API you suggest) to create the mailbox, store credentials securely, and return a success message. A clean, mobile-friendly form, basic validation, and error handling are essential. I also need a lightweight admin view so I can see, disable, or delete accounts if needed.
