cPanel / Exim Email Deliverability Expert Needed – 554 Errors Description: We are looking for an experienced cPanel/Exim email server specialist to troubleshoot an inbound email delivery issue on our company domain. Our company emails are working normally and we can receive emails from most external senders. However, emails from one specific government organization are being rejected or delayed by our mail server. The sender is using Proofpoint, and they are receiving errors such as: * 554 5.1.2 < #5.1.2> * 554 5.4.0 < #4.2.0> Our current setup: * cPanel hosting * Exim mail server * MX points to our cPanel mail server * Email Routing: Local Mail Exchanger * cPanel Email Deliverability: Valid * SPF, DKIM and DMARC configured * Other external emails are being receive...

A fresh AlmaLinux 10 server is waiting to be transformed into a production-ready shared-hosting node. The work starts with clean installs of cPanel/WHM, LiteSpeed Web Server, and CloudLinux, followed by enabling WHM’s reseller features and deploying WHMCS for automated billing and provisioning. After the installs, create the actual hosting packages inside WHM and replicate them in WHMCS so new orders are pushed straight to the server without manual intervention. Please deliver the job fully configured, security-hardened, and performance-tuned, then run a test signup to prove that WHMCS, WHM, and LiteSpeed are talking to each other correctly. Deliverables • Installed and licensed (our keys) copies of cPanel/WHM, LiteSpeed, CloudLinux, and WHMCS on AlmaLinux 10 • WH...

I need a fresh SMTP server configured and fully integrated with my existing cPanel account so I can push roughly 1 000–10 000 emails per day through Webmail without bumping into the usual sending limits. There is no current SMTP service in place, so the job starts from scratch: provisioning the server, linking it to my domain inside cPanel, and making sure every authentication layer—SPF, DKIM, DMARC, rDNS—is properly applied for strong inbox placement. Once it is live, I want to be able to open Roundcube (or any default Webmail client that ships with cPanel) and send campaigns confidently, knowing throttling is no longer an issue. Please secure the server, tweak Exim or Postfix for high-volume performance, and leave me with clear, concise notes on how to add future domai...

I already own the domain; now I need a fully-operational MailWizz environment that I can start using the moment you hand it over. You will supply and configure everything—dedicated Windows server, clean IP address, valid MailWizz license, and any underlying mail transfer agent—so I don’t have to purchase additional components or subscriptions. The build must be optimised for high-volume transactional emails. Rather than relying on third-party relays like Amazon SES, SendGrid, or Mailgun, I’d like to send directly through MailWizz itself, so please install and tune the SMTP/MTA you feel delivers the best inbox placement on a Windows stack. Key deliverables: • Provisioning of a Windows server with a fresh IP • Installation and activation of MailWizz unde...

I’m building a dedicated marketing-email blaster and need a developer who lives and breathes Node.js. The core goal is simple: take a clean list of contacts and push out high-volume campaigns reliably, with full control from my own interface rather than a hosted platform. Your brief • Build the entire sending engine in Node.js, tuned for speed, stability, and deliverability. • Connect the engine to at least one third-party SMTP or API-based provider of your choice (I’m flexible here, as long as the integration layer lets me swap providers later). • Provide a minimal web dashboard where I can paste or upload a list, compose an HTML template, hit “Send” and watch progress in real time. Deliverables 1. Production-ready Node.js codebase (well-commen...

I’m preparing a month-long promotional email campaign and need a rock-solid SMTP server built on Amazon SES that can push high-volume sends without hitting daily ceilings. The server must stay healthy, inbox-friendly, and fully operational for at least 30 days. Here’s what I expect from you: • Provision or configure a VPS (or comparable environment) and tie it to my Amazon SES account. • Complete both domain verification and DKIM alignment so the sender reputation starts off clean. • Optimise all SMTP, SPF, DMARC and bounce/complaint settings for promotional traffic. • Hand over working SMTP credentials plus a brief how-to so my team can plug the server into our mailer right away. • Run test sends with me to confirm inbox delivery before sign-...

I run all of our transactional and marketing messages through a custom-built SMTP server, and I now need every single message we send to show a new “from” address. That address has not yet been added or verified on the server, so the first step will be setting it up properly, completing whatever SPF, DKIM, and verification steps are required, then updating the server configuration to make it the default sender. Once the address is live and trusted, I want the change enforced globally—no edge cases where an older identity slips through. After you update the SMTP settings, I’ll need a quick proof: send a few sample messages my way and show the headers so I can see the new address, correct DKIM signature, and a pass on SPF. If you have experience with Postfix, Exim, ...
