Please build, configure, and fine-tune everything so the service runs smoothly with no username-and-password layer (that requirement is intentional because the environment is fully firewalled on our side). The core of the job is the full installation and optimisation of the SMTP engine you feel is best for Windows—MailEnable, hMailServer, PowerMTA, or another proven option are all fine as long as deliverability is strong. I also need the surrounding essentials: correct PTR, SPF, DKIM, and DMARC records, IP warming guidance, plus any queue-management or throttling tweaks that help ke...
I am looking for an experienced developer to help migrate 3 existing websites/domains from our old projects to new projects and make sure everything continues working perfectly before and after the migration. The work includes: * Move/connect the existing domains from the old projects to the new projects * Configure DNS, SSL and all required domain settings * Make sure there is no unnecessary downtime during migration * Set up Google Search Console for each website/domain * Set up Google Tag Manager for each website * Set up Google Analytics 4 for each website * Configure and verify the required conversion/event tracking * Make sure the tracking can later be used correctly with Google Ads * Replace/update several images and backgrounds inside the admin sections so that the visual assets ...
I’m drowning in junk that keeps slipping into the work mailboxes on my own domain, so I need an email-security specialist to tighten things up fast. The accounts are not on Gmail or Outlook; they’re hosted directly on my domain, and right now the basic filtering isn’t doing the job. Here’s what I’m after: audit the existing server set-up, update any DNS records (MX, SPF, DKIM, DMARC), tune or replace the current spam-filter rules, and leave me with a clean inbox that still accepts every legitimate message. You’ll get temporary access to the control panel and DNS so you can: • Inspect mail logs and current filter scores • Correct or add SPF, DKIM and DMARC records • Configure SpamAssassin (or a similar tool) and fine-tune thresholds ...
Our company mailbox on an Ionos-hosted server is being flooded with unwanted messages and I need an expert to stop them quickly and cleanly. The mail flow passes through Ionos before it reaches Microsoft Outlook on the desktop, so whatever you implement must sit at server level and not rely on individual client rules. What I already know • The problem is on the company email server, not a personal inbox. • We run on the Ionos mail platform (not Exchange or Google). • Spam ranges from phishing attempts to the usual marketing clutter—if it’s malicious, I want it blocked; if it’s legitimate but irrelevant, I want it routed to junk automatically. What I’m hoping you will do 1. Audit current MX, SPF, DKIM and DMARC records, then correct or harden...
I need a specialist to configure and verify DNS settings on my domain to ensure seamless integration with three SMTP providers: AWS, MailGun, and Brevo. The tasks include setting up SPF, DKIM, and DMARC records, ensuring all configurations are correct, and conducting thorough testing to confirm functionality across all providers. I am facing issues with domain verification due to incorrect DNS details. I need assistance in resolving this and ensuring proper configuration for AWS, MailGun, and Brevo.
I need my primary website domain—together with the web-app that sits on it—moved from GoDaddy over to Cloudflare. The site is running smoothly right now; there are no performance or security problems, and I’m not looking to introduce any redesigns or feature upgrades during the move. The job is purely about shifting the DNS and gaining the benefits of Cloudflare’s management and protection without causing downtime or service interruption. I will give you full access to the GoDaddy dashboard and will add you to my Cloudflare account so you can replicate every current record and point traffic correctly. Deliverables • Complete transfer of the domain and all DNS records from GoDaddy to Cloudflare • Validation that the site and app resolve exactly as b...

I need someone to clone my current website from base44 and rebuild it using my own domain name without any subdomains.

I need a self-hosted SMTP environment that can reliably push up to 10,000 messages a day straight into Gmail, Outlook, and Yahoo inboxes. The core objective is a rock-solid sender reputation, minimal spam-folder drift, and the flexibility to scale further once the infrastructure proves itself. The server must be fully authenticated: • DKIM (DomainKeys Identified Mail) • SPF (Sender Policy Framework) • DMARC (Domain-based Message Authentication, Reporting & Conformance) Beyond those records, I expect proper rDNS, custom HELO, feedback loop registration where available, and a clear IP-warm-up plan. Please outline the MTA stack you believe is best suited—Postfix, Exim, or any other you trust for deliverability—and how you will harden it against blacklis...
I need a production-ready SMTP server that can reliably push 3,000+ messages every day while keeping at least 90 % of them in the primary inbox, not the spam folder. The environment must be properly authenticated with DKIM, SPF, and DMARC, and every connection secured over SSL/TLS. I will restrict access to approved addresses only, so IP whitelisting and individual user log-ins are mandatory. Here is how I picture the engagement: • You install and configure the MTA (Postfix, Exim, PowerMTA or similar—happy to hear your recommendation) on a VPS or dedicated machine I will provision. • You generate and publish the DKIM keys, set the SPF record, and create a DMARC policy that balances protection with delivery. • TLS certificates are installed, and the server listens...
I need Amazon Simple Email Service configured from scratch so I can reliably distribute large-volume transactional emails. Once the SES account is live, I want it wired into my existing Outlook environment, giving me the ability to compose, send, and track those messages straight from my familiar inbox. Core tasks include verifying my sending domain, setting up SPF, DKIM, and DMARC, requesting any necessary sending-limit increases, and ensuring the account is properly warmed up so daily throughput is never throttled. After the backend is stable, please connect SES to Outlook (desktop 365) using SMTP or another proven method, then demonstrate a successful test send so I can see delivery metrics inside the AWS console. Deliverables • Fully verified and production-ready Amazon SES ac...
I’m looking for an experienced network and system administrator to take full ownership of our small-to-mid-sized office network. The environment is being refreshed from the ground up, so I need help at every stage: • Hardware deployment and configuration – routers, switches, wireless access points, and firewalls all need clean, standards-based builds. VLAN design, IP addressing, DHCP/DNS, and basic cabling checks are part of the work. • Performance monitoring – once the gear is live, I want continuous visibility. Please integrate the hardware into the monitoring stack of your choice (SolarWinds, PRTG, Zabbix, or similar), set sensible alerts, and give me a weekly health summary during the first month. • Security hardening – enforce best-practi...
My outbound mail reaches Gmail and every other provider perfectly, yet anything sent to Outlook, Hotmail or (Microsoft) still heads straight to junk or they don’t get it at all . The domain is hosted on delicated server from and I have full access to all DNS and server-side settings, so making technical changes is not an issue. SPF, DKIM and DMARC are already correctly published and passing; Microsoft support tickets have been opened more than once, and I have tweaked header settings, sending patterns and content, but the problem always returns. I want a definitive fix that keeps the domain off Microsoft’s spam list for good, not a temporary workaround. Here is what I need from you: • A comprehensive audit of my current configuration, including header analysis, send...
