About

I’m Ketan Aagja — Manager IT with more than 15 years of experience in network technologies and infrastructure.

Everything here comes from real life experience: mail servers I actually run, configurations I actually deployed, and the scripts I wrote to stop doing the same job twice. No credentials, no theory — just what worked on production systems and why.

Most of it is Linux, Zimbra, Dovecot, Postfix, OpenLDAP and iRedMail. If something here saves you an afternoon, it has done its job.
