  • I used to use postfix, dovecot, spamassassin. I then moved from dovecot to exchange for better web client and sharing capabilities. I got fed up with the constant chasing of patches for Exchange that needed more than just an installer, they needed reg fixes, DNS updates, certificate changes etc. I ended up moving my family to 365 with free licenses to spare me the hassle.


  • Monitoring is the key. I use Zabbix, but essentially you want to gather metrics and report on issues.

    Once things are set up and working, even with 10s of VMs and applications, it’s quite reliable. The biggest things that catch you out are updates breaking functionality, updates requiring additional manual steps, running out of disk space or expired certificates.

    I find I get a spurt of energy to recreate or implement a new system every few months but things just tick over in the meantime.
