Hi all we had all this working yesterday but I changed some DNS settings to get a local printer working and it may have disrupted the normal operation of the server. I am currently dealing with an issue where my centOS mail server has just gone offline. It seems to be a connection issue as the error message I am receiving is that connection is timing out. This issue started occurring right after some changes were made to the server configuration. Specifically, some settings were modified which seems to be the root of the problem. I need an expert who can swiftly and accurately identify the problematic changes and rectify them. Key Qualifications: - Strong knowledge on centOS mail server configurations - Experienced in troubleshooting and resolving mailserver issues - Expertise in server and network configurations - Previous experience in fixing similar issues successfully. The freelancer should possess proactive communication skills, be prompt and efficient. The work needs urgent attention. Deliverables are: 1) Get our operational mail server working and being found on the web 2) Fix servers DNS especially host name 3) get Name servers operational and server discoverable.
