Open Source based Mail Server Management
Posted by: Lans in Case Studies on February 1st, 2009
Virus attacks and spam mails create havoc in an enterprise. Heavy spam may lead to work hindrance and server downtime. Tackling this problem effectively is therefore very important if you want to maintain your enterprise efficiency. Our Enterprise Mailing Solutions are an apt answer to this problem.
Providing a range of mail-related services expected by organizations can be a daunting process. Our Enterprise mailing Solution presents a comprehensive guide to manage the most important e-mail services. Open Source offers customized mailing systems with high ROI and low TCO, starting from small organizations to large enterprises. We implement Open Source mailing servers using basic MTA’s Sendmail and Q-Mail along with integration of add on services / products like Spam assassin, Clam antivirus, Squirrel mail, LDAP etc.
Beginning with installation and configuration of the popular server-based operating system Fedora Core, we assist in outlining the system and network preparation process geared towards running a complete enterprise e-mail system.
We specialize in Installation and configuration of the following:
- Qmail
- Sendmail & Squirrelmail
- POP3/IMAP server Dovecot
- Clam Anti Virus, Spam Assassin for virus protection and spam filtering
With a nod to the global e-mail availability now required by many organizations, we also guide you through configuration of a web-based mail interface, mailing-list software, and advanced security and privacy topics.
Remote Server Management
Posted by: Lans in Case Studies on February 1st, 2009
Vigilance is necessary for maintaining the health of the IT environment in any organization. But generally, organizations lack the expertise or necessary resources to do so. If you are focusing your precious time and resources on monitoring the system and resolving server management related problems, you are wasting crucial time and jeopardizing your long-term business prospects.
Metatron Labs is here for you so that you can concentrate more on your core business and leave server management and monitoring to us. Tetra has been managing mail server for some reputed ISP providers like YouTele, VSNL, Hathway, Bharti, We have got complete Infrastructure to provide 24X7 support with 3 levels of technologists available.
We provide a comprehensive range of solutions and support options. Qmail server management is one of the services that we believe is helpful in case of ISPs and web hosting. We build our messaging solution around Qmail having SMTP/SMTPs, POP3/POP3s and IMAP/IMAPs access. Qmail provides backend connectivity to LDAP, MySQL, Oracle, Plain text, CDB, password etc.
Many Webmail scenarios like Squirrelmail, Sqwebmail, Open Webmail, and IMP over horde is supported and customized by us to suit the required deliverable. Collaborative environments are also deployed by as using open-source environment likeopen-groupware,e-groupware, and open-xchange.
Benefits of Our Remote Management Services
- Helps identify problems before they actually occur as experts monitor and troubleshoot your network systems.
- Smoother running networks allow less down time for the employees.
- Any eventual problems are resolved faster as experts in the domain efficiently handle them.
- It helps to free your staff from monitoring functions and spending time and resources on solving computer problems.
- Have access to up-to-date security software and virus protection software.
- Lastly, you have the confidence that the domain experts properly look after your systems and you therefore, can concentrate on the business in hand without worrying about your server health.
- Automation of the configuration and provisioning of the server.
- Minimizing the cost and time taken associated with the task.

Our Full System Backup uses the readily available Rsync utility to transfer your data to our server. We fully configure the backup for you based on your needs, provide the transfer of the data to our servers, and provide monitoring to insure backups are valid and occurring at regular frequencies
Essential Linux Hardening
- BFD – (Brute Force Detection) – Most Linux servers on the Internet are attacked by brute force multiple times each week. BFD detects brute force connections and automatically enters the offending IPs into the firewall to be blocked.
- SSH Server Hardening – Locks down and hardens the SSH server. Provides additional protection against brute force attacks.
- Firewall Installation – APF (Advanced Policy Firewall) iptables based firewall and anti-dos rule sets.
- LES – (Linux Environment Security) – Enforces root-only permissions on system binaries as well as other restrictions on system programs.
- /tmp, /var/tmp and /dev/shm Hardening – The /tmp, /var/tmp and /dev/shm directories are the most common cause of security compromises on web hosting servers. Hardening prevents execution of malicious scripts from being launched from these directories.
- Disable Unused Services/Software – Unused services and software are disabled to prevent them from being exploited.
Advanced Linux Hardening
- Everything in the Essential Linux Hardening
- Mod-Evasive – Blocks HTTP Denial of Service attacks.
- IM – (System Integrity Monitor) – Automatically monitors and restarts required services including HTTP, FTP, DNS, SSH, and MYSQL.
- LSM (Linux Socket Monitor) – Identifies and alerts you when rogue services are started on your server
- SPRI – (System Priority) – Sets the priority to current processes being run on your server, decreasing load 5-25%
- PSAD – Detects port scan attacks and and automatically enters the offending IPs into the firewall to be blocked.
- CHKRootKIt – Simple script that detects software used by hackers. It scans once a day and emails the client if any suspicious scripts are found.
