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 • Set up or update blacklists, whitelists and any reputation services • Provide a concise summary of all changes and simple maintenance tips I’d like minimal downtime and a quick test report at the end showing the drop in spam. Let me know your experience with custom-domain email hygiene and how soon you can start.

Before touching anything I'd pull headers from a sample of the junk that's landing, because the fix depends entirely on what's getting through — spoofed mail claiming to be from your own domain (very common when DMARC is absent or set to p=none), a catch-all address harvesting everything sent to your domain, or genuine bulk mail scoring too low. From there I'd correct SPF, add DKIM signing and roll DMARC out in monitoring mode first so we can see reports before enforcing, rather than jumping to reject and silently losing client mail. Then SpamAssassin threshold tuning with RBLs, greylisting and Razor/Pyzor, plus a before/after spam-catch report. Minimal downtime since DNS changes are additive. Can start right away.

Hi, I can audit and tighten your custom-domain email setup at the server level, with the goal of significantly reducing spam while protecting legitimate business emails. I’ll start by reviewing the current mail-server configuration, DNS records, mail logs, filtering scores, and delivery patterns to identify where unwanted messages are getting through. I’ll then handle: * Audit and correction of **MX, SPF, DKIM, and DMARC** records. * SpamAssassin or equivalent filtering configuration and threshold tuning. * Review and cleanup of existing blacklists, whitelists, and filtering rules. * Identification of recurring spam/phishing patterns and appropriate server-side blocking. * Review of mail reputation and authentication failures. * Testing inbound/outbound delivery to minimize disruption and avoid false positives. * Before/after comparison of spam volume where mail logs provide reliable measurements. I’ll make changes carefully with rollback considerations and avoid unnecessary DNS or mail-server downtime. At completion, you’ll receive a concise report documenting the changes, recommended settings, and simple instructions for maintaining the filters. I have hands-on experience with cPanel/WHM, DNS, SpamAssassin, SPF/DKIM/DMARC, mail troubleshooting, and server-level email security. I’m available to start immediately and can begin with the audit as soon as temporary access is provided. Ali Asif

Hi, I can help you cut down the spam flooding your work mailboxes. On a self-hosted domain, this usually comes down to tightening up mail server configuration and adding proper filtering layers. I'd start by reviewing your current setup on the Linux server, then implement or tune spam filtering tools like SpamAssassin or rspamd. From there, I'd check that your mail records are properly configured to help reject spoofed messages before they even land in your inbox. I've handled similar troubleshooting and technical support tasks on Linux servers, so I'm comfortable digging into mail logs and server configs to find where the junk is slipping through. Happy to discuss the specifics through Freelancer messages and get this sorted for you. Best regards, Hector

Spam reaching Outlook is the symptom — the mail path is where we fix it. We’ll audit MX/SPF/DKIM/DMARC, harden IONOS server-side filtering, verify legitimate delivery, then monitor the result for 48 hours. We stay with the problem until the cause is isolated and the solution is proven, not just configured.

Hi, Email security hardening with SPF, DKIM, DMARC and SpamAssassin tuning on a custom domain is something I can sort out quickly and cleanly. I will audit your current mail server setup and logs to see exactly what is getting through and why.

The whole process will be done with minimal downtime and you will get a concise summary of every change made plus simple maintenance tips so your internal team can manage it going forward. I will also run a quick test report at the end showing the before and after spam drop. Price: $25 to $30 One question: what control panel is your hosting using — cPanel, Plesk, DirectAdmin or something else? That will help me confirm I can access everything needed before we start.

⭐⭐⭐⭐⭐Hi, I recently worked on Linux server and email infrastructure projects involving DNS configuration, SMTP services, authentication, and mail-delivery troubleshooting. The key here is improving spam detection without creating false positives, so I would first analyze the existing mail flow and filtering scores before changing thresholds. I can audit your mail server, verify and correct MX/SPF/DKIM/DMARC records, tune SpamAssassin rules, and configure appropriate blacklists and whitelists. I’ll also review mail logs and test legitimate and spam messages to ensure the filtering behaves correctly. I’ll work with minimal disruption, provide progress updates while making changes, and finish with a clear test report and maintenance notes. I can start quickly and focus on measurable improvement rather than simply changing settings. Thanks
