mail-related, and another user who struggles to remember in which
logfile $DIFFICULT_TO_CLASSIFY_PROGRAM might be writing its logs.
There are log readers like "lnav" and "multitail" that will become useless
without traditional log files. "lnav" tails multiple logs by default and IMHO
provides a very useful interface.
Exclusively relying on systemd logging facilities limits ways in which we can
analyse logs.
