We need someone experienced in domain removal; we don't work with beginners, as our problem is quite complex. We've tried several methods such as: The website has been cleaned and secured: Removed unwanted files and suspicious scripts Reviewed server logs and website indexes Updated security configurations to prevent future abuse Email security protection has been properly configured: SPF enabled DKIM enabled DMARC enabled But all of them were rejected by spamhaus. We strongly suspect that someone is maliciously sending spam emails containing our website information, thus triggering a DBL (Domain Blocking and Blinking) attack.
I want to run marketing campaigns from my own infrastructure rather than relying on third-party mailers, so I need a fresh Amazon SES (SMTP) environment built from scratch. I do not yet have an AWS account, so the first step will be guiding me through account creation, basic security hardening, and verifying my identity with Amazon. Once the account is active, I will rely on you to move the domain into SES, set up SPF, DKIM, and DMARC records, request production access, and secure the SMTP credentials. Please handle every configuration step necessary so I can plug the final host, port, username, and password directly into my email automation tool and start sending marketing emails without landing in spam. Deliverables will be straightforward: • A brand-new AWS account ready for bill...

I Wan to develop a mail sever. And link it with lintmonk I have vps, cpanel I want to develop it for cold marketing.
Every marketing message I send—currently fired off manually from my Gmail account—lands in the recipient’s spam folder. I haven’t put any safeguards in place yet (no SPF, DKIM, or DMARC records), and I’m debating whether shifting everything to Outlook/Microsoft 365 would help. I need someone who can: • Analyse my sending domain, IP reputation and content to pinpoint why Gmail is being flagged • Configure and verify SPF, DKIM and DMARC correctly, then guide me on list-hygiene and sending-frequency best practices • Compare Gmail versus Outlook deliverability for my use case and outline a clear, low-disruption migration path should Outlook prove the smarter option Once the fixes are applied, I want to see a measurable jump in inbox placeme...
# URGENT: Help Recover Website & Email Services (Domain/Hosting Issue) I am urgently looking for an experienced system administrator / hosting expert / domain specialist to help recover my website and business email services. ## Situation My domain is: My hosting provider is Mherhost (possibly connected with ). Since the digital blackout in Iran, my website and all connected email accounts have gone offline and I have no access to the hosting provider anymore. I do NOT live in Iran and currently cannot contact them properly. My business is being seriously affected because: * Website is down * Business emails are inaccessible * I may lose important client communications * I already paid hosting/services until January 2026 ## What I Need I need someone experienced with: * Doma...
My outgoing messages from Google Workspace often land in spam and I need that fixed. I want to begin by sorting out SPF—please confirm whether any record already exists and adjust or create it so it passes every check. Once SPF is solid, move straight on to DKIM and DMARC so the whole domain is protected and aligned. What I need from you: • Detect any current SPF record, explain its status, then publish a fully-compliant version in DNS • Generate and add the correct DKIM key through the Workspace admin console, verifying that it propagates • Create a DMARC policy that balances protection with deliverability, plus guidance on reports • Run end-to-end tests (Google Postmaster Tools, MXToolbox, etc.) and share the before/after results I’ll supply DNS...
I’m in the middle of a full rebrand and need a smooth technical hand-over. The new domain has been purchased but nothing else is in place yet. Here’s what I need from you: • Configure a reliable shared hosting plan, point the domain DNS correctly and make sure SSL is active from day one. • Create 1–5 new company email addresses under the new domain and route them through Gmail so we can keep using the familiar Google interface. Please include SPF, DKIM and DMARC records so mail lands in the inbox, not spam. • Provide a short hand-off document (or quick Loom video) that shows where everything lives—cPanel access, DNS zone, and Gmail settings—so my team can manage things later. If you prefer specific tools—cPanel, Plesk, Cloudflare, et...
Our regional payment subdomain is being flagged by Google Safe Browsing and other security filters as a "potential phishing threat," preventing members from processing payments.

I run all outbound messages through a custom SMTP server, yet too many land in spam and certain promotional sequences show the lowest open rates. I want a clear, data-backed explanation of why this is happening and a concrete path to reliable inbox placement. The scope covers a full inspection of the delivery stack: authenticating SPF, DKIM and DMARC records, DNS propagation, mail-server and MTA settings, sending cadence, IP and domain reputation, blacklist status, and the raw headers produced by each message type. Once root causes of the spam placement are identified, the fixes should be applied and verified. Deliverables • Detailed audit report that maps every issue to its impact on deliverability and lists actionable fixes in priority order. • Corrected and fully ali...
I need an experienced Linux systems administrator to set up a new server with a proper Fully Qualified Domain Name (FQDN) and perform a clean installation and configuration of cPanel & WHM.

My dedicated server has suddenly gone offline and WHM now returns a “Server not found” error. I have not tried any troubleshooting yet and, crucially, I do not have backups, so every cPanel account currently hosted must remain intact. I need an experienced systems administrator who can: • Diagnose why WHM is unreachable (network, DNS, service failure, firewall, corrupted files, etc.) • Bring the server back online quickly and verify WHM loads normally • Ensure all existing cPanel accounts, site data, and email remain untouched and fully functional after the fix A rapid response is essential. Please outline how soon you can start, the steps you would take to safeguard data, and any similar recoveries you have handled.
My newsletters keep ending up in Gmail’s promotions or spam sections, even though I have Cloudflare managing my DNS and Valimail for authentication. I need a specialist who can review and correct every setting that affects sender reputation so the bulk of my sends land squarely in the primary inbox. Here’s where things stand: • DNS for the domain is routed through Cloudflare. • Valimail is already connected, but I’m not confident SPF, DKIM, DMARC, and BIMI are passing exactly as Gmail expects. • All traffic is newsletter-style content, and deliverability problems happen frequently. What I expect from you: 1. Audit the existing DNS records in Cloudflare and my Valimail dashboard. 2. Generate and publish any missing or sub-optimal SPF, DKIM, DMARC, or...
