[CentOS] Postfix and choice of RBL

2019-06-17 Thread Nicolas Kovacs
Hi, I'm managing several mail servers running CentOS 7, Postfix and Dovecot. SpamAssassin is filtering mail nicely, but I'm considering using RBL (blacklists) to take some load off the servers. General question to those of you who use RBL. Which lists do you recommend using? Cheers, Niki -- Mi

I found that one of my users' workstation is, for some reason, running systemd-sleep. I cannot find, anywhere on the system. system-sleep.conf (or systemd-sleep.conf), nor do I find systemctl status system[d]-sleep. How can I turn this thing off, other than renaming /usr/lib/systemd/systemd-sleep?
