Warning.... Long time none active person here! Why?? Servers (Debian with ISPconfig) have been running great, and had absolutely no issues with them... ..... I've installed a new server (Debain 10) some weeks ago, and this one is giving me a hell of a time! I used Till his excellent howto (The Perfect Server - Debian 10 (Buster) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.1) to install the server. As mentioned above.... I'm having a hell of a time with this server. Normally I would reinstall something like this, but as it's in production now and as I do not want to migrate all the users again I hope that someone here can help me with one of the issues I'm having with the server. Okay. Here we go. I'm seeing every 2 minutes the following error in /var/mysql/error.log Okay.. Not much info.. So.. Looking at /var/log/syslog, I see that at this time interval postfix is doing it's thing. Anyone here who might have a clue here where to look, and how to fix this?
