My Zimbra installation has suddenly started dropping messages in both directions—nothing is reliably coming in or going out. I’m looking for someone who can jump straight into troubleshooting mode, sift through the logs, queues, and MTA settings, and pinpoint why messages are stalling or disappearing. Key details you should know: • The problem affects both inbound and outbound mail, so I suspect it could be DNS-related (SPF, DKIM, DMARC), queue corruption, or a misbehaving transport rule. • I have root and admin access ready for you as soon as we begin. • The goal is a clean bill of health: messages accepted, queued, and delivered without delay, with clear documentation of what was fixed so I can avoid a repeat. Deliverables 1. Root-cause analysis with log references 2. All corrective actions applied (Postfix, Anti-Spam/Anti-Virus, DNS records, etc.) 3. A brief hand-over document summarising changes and any follow-up recommendations I’m ready to start as soon as you are.

As a seasoned Full Stack Developer, my troubleshooting and systems management skills have always been at the forefront of my work. I specialize in analyzing intricate systems to identify root causes of problems, much like the challenges you're experiencing with your Zimbra installation. My extensive experience includes resolving issues with DNS (SPF, DKIM, DMARC), performing queue recovery, and investigating transport rules for misconfigurations. With the appropriate system access, I can efficiently generate log analysis reports and dig deep into your Mail Transfer Agent settings to identify all factors contributing to message delays or vanishing. I will then proceed to implement robust measures such as applying corrective actions on Postfix, tuning Anti-Spam/Anti-Virus protocols and modifying DNS records where necessary. To round up my services, I will provide you with a comprehensive hand-over document that summarizes all implemented changes during the resolution process and any follow-up recommendations that would help ensure seamless operations moving forward. The goal is to give you a clean bill of health for your email delivery system while empowering you with knowledge to avoid future recurrences. Let's get started!

Hi, When Zimbra drops both inbound and outbound mail, the issue is usually within the MTA layer (Postfix), DNS authentication records (SPF/DKIM/DMARC), queue corruption, or a service that has silently failed. Since it’s affecting both directions, I’ll approach this as a full mail flow audit rather than a surface-level fix. I’ll begin by inspecting mail logs, queue status, and Postfix configuration to identify where messages are stalling or being rejected. From there, I’ll verify DNS records, check DKIM signing, confirm proper MX routing, and ensure anti-spam/anti-virus services aren’t interfering with delivery. If there’s queue corruption or transport misconfiguration, I’ll repair and revalidate the mail flow end-to-end. You’ll receive a clear root-cause explanation with log references, all corrective changes applied, and a short hand-over document outlining what was fixed and how to prevent recurrence. I’m ready to start immediately once root and admin access are provided. Thanks.
