I want a complete, ready-to-use SMTP server that lives on my Windows machine and lets me push out high-volume campaigns without the usual caps yet still places messages in the inbox, not the spam folder. 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 keep reputation high when volumes spike. Acceptance criteria • SMTP service runs as a Windows service, auto-starts at boot, and accepts unauthenticated connections from our internal network. • Domain records you supply validate without errors and pass standard tools such as MXToolbox. • A live test campaign to Gmail, Outlook, and Yahoo inboxes lands in Primary/Inbox (you can hide real addresses in screenshots). • A short hand-off document explains where configs live, how to restart the service, and how to adjust sending speed. If you’ve delivered similar high-inbox bulk solutions before, I’d love to hear a brief outline of your approach and estimated turnaround.

Hello, "Optimized Windows SMTP Server" - you need high‑volume bulk email that lands in inboxes without authentication. I’ll deploy hMailServer on your Windows box, set up SPF, DKIM and DMARC records, and configure a dedicated IP with proper PTR. Using queue‑management tweaks I’ll keep reputation high during spikes, and I’ll script a simple restart service to auto‑start at boot. This matches my experience automating email‑related workflows and handling DNS/Security configs. One edge case: unauthenticated access can be abused if the firewall rules are too open – I’ll lock the service to your internal subnet only, preventing external abuse while keeping the required open access. Which domain will the server send from, and do you have a dedicated IP ready for the PTR record? Looking forward to working with you. Artur Giżycki

Hi there, Based on my understanding, you need a Windows-based SMTP server configured for reliable high-volume email delivery, including the SMTP engine setup, DNS authentication, queue management, throttling and monitoring. I can configure the SMTP environment as a Windows service with appropriate SPF, DKIM, DMARC and PTR records, along with sensible queue and rate-management settings to maintain sender reputation. I can also provide IP/domain warming guidance and test the configuration with major mailbox providers. I would recommend keeping the server restricted to your trusted internal network and following opt-in/anti-abuse requirements rather than relying on authentication bypasses or spam-filter evasion. A couple of questions I would like to clarify: 1. Which Windows version, sending domain and dedicated IP are available for the SMTP server? 2. What approximate daily/monthly sending volume and email type (transactional, opted-in marketing, etc.) do you expect? There are a few other details I’d like to discuss around the SMTP software, DNS/provider access, network restrictions, sending volume and testing before confirming the exact configuration and timeline. Please open a chat with me so we can review the environment and finalize the setup approach.

I understand you need a Windows-based SMTP infrastructure for legitimate high-volume campaigns, restricted to your internal/firewalled network, with strong deliverability configuration and a clear handover. • Install and configure a suitable Windows SMTP engine based on your expected volume and infrastructure • Run SMTP as an auto-starting Windows service • Restrict unauthenticated relay strictly to approved internal IPs/subnets to prevent open-relay abuse • Configure and validate SPF, DKIM, DMARC, PTR/rDNS and related DNS requirements • Set up queues, retries, bounce handling, connection limits and provider-aware throttling • Provide responsible IP/domain warming guidance to establish sender reputation gradually • Test delivery across Gmail, Outlook and Yahoo and diagnose authentication/reputation issues • Validate DNS/authentication using standard deliverability tools • Optimize for legitimate opt-in email while respecting provider limits and anti-spam requirements • Provide handover documentation covering configs, restarts, queues and sending-rate adjustments • Clear communication, quality work and revisions if needed • I can start immediately Approx. timeline: 2–4 days, plus ongoing IP warming. Inbox/Primary placement cannot be guaranteed because recipient providers ultimately control filtering. Message me with your Windows/server, domain, IP and expected sending-volume details to get started.

Build and harden a Windows-based bulk SMTP setup optimized for inbox delivery. I’ll install the best-fit SMTP engine (MailEnable / hMailServer / PowerMTA or another proven Windows option), configure it as a Windows Service with automatic startup, and enable unauthenticated submissions strictly from your internal network (firewalled environment). Deliverability focus: correctly wired DNS dependencies (PTR, SPF, DKIM, DMARC), validated record formats, and configuration that avoids common inbox-failure patterns. I’ll provide IP warming guidance, queue/throttling and reputation-safe pacing to handle volume spikes, plus sensible retry/backoff tuning. Testing: run a controlled live campaign to Gmail, Outlook, and Yahoo inboxes and capture proof via screenshots (with addresses hidden). Acceptance includes MXToolbox-standard record validation without errors. Handoff: a concise document naming config locations, service restart steps, and a sending-speed adjustment guide (throttle/queue parameters).

Hi there! I understand you need a reliable Windows-based SMTP setup for high-volume email delivery, with correct DNS, queue management, and strong sender reputation. The important part is achieving reliable delivery without creating reputation or security problems, especially when sending volume increases. I have experience with Windows Server, SMTP configuration, DNS, SPF, DKIM, DMARC, mail queues, throttling, monitoring, and email infrastructure. My approach will be to install and configure a suitable SMTP platform as a Windows service, secure internal unauthenticated relay access by network rules, configure SPF/DKIM/DMARC and PTR requirements, and tune queues and sending rates. I will also test delivery to major providers and provide clear handover documentation. I will focus on legitimate opt-in sending and sender reputation rather than bypassing provider spam controls or inbox filtering. check our work https://www.freelancer.com/u/ayesha86664 Do you already have the sending domain and dedicated public IP available for the SMTP server? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

⚠️ Please pay when you are satisfied with the project.⚠️ I can help build a properly configured Windows SMTP environment for legitimate, permission-based email delivery, with reliability and security treated as core requirements. Your project requires a Windows service with internal-network access, correct PTR/SPF/DKIM/DMARC configuration, queue management, throttling, and operational documentation. I understand that deliverability depends on sender reputation, recipient engagement, authentication, and provider policies, so inbox placement in Gmail, Outlook, or Yahoo cannot responsibly be guaranteed or engineered around spam filters. I would configure the SMTP engine, DNS authentication, monitoring, queues, rate controls, and automatic service startup, then validate configuration and delivery through authorized test accounts. I would also document configuration locations, restart procedures, and sending controls for future maintenance. Is the intended traffic strictly opt-in or transactional email? Which domain and dedicated sending IP will be used?

I can set up a Windows-based SMTP service for legitimate opt-in or transactional sending, with unauthenticated relay restricted strictly to your trusted internal network/IP range. I would configure the SMTP engine as a Windows service with auto-start, queue management, throttling, logging, bounce handling, and IP/domain restrictions to prevent open-relay abuse. I’ll also provide the required SPF, DKIM, DMARC, MX/PTR guidance and verify the DNS configuration. For deliverability, I’ll tune sending rates, reputation controls, retries, and warm-up strategy, then test delivery to major providers such as Gmail, Outlook, and Yahoo. I can optimize for inbox placement, but no responsible setup can guarantee Primary/Inbox placement because recipient providers make the final decision. You’ll receive the working configuration, DNS records, test results, and a concise handover covering service restart, configuration locations, queues, logs, and sending-rate changes. I have experience with SMTP, Windows Server, DNS, email authentication, deliverability, and secure mail-server configuration.

I’ll also provide an IP/domain warming strategy and conduct controlled delivery tests to Gmail, Outlook, and Yahoo. I’ll document the results clearly, while noting that final Inbox/Primary placement is controlled by each mailbox provider. The hand-off document will cover configuration locations, service restart commands, sending-speed adjustments, DNS requirements, monitoring, and troubleshooting. Estimated turnaround: 2–4 business days, depending on access to the Windows server, DNS, public IP, domain, and expected sending volume.
