With systemd logging, logs are by default lossy (rate-limits too tight

System-wide "defaults to 10000 messages in 30s" and "is applied per-
service", so this can be easily resolved by providing postfix.service
with:
LogRateLimitIntervalSec=0
I think the point is that before journald took over logging everywhere
no syslogd (that I'm aware of) did rate limiting like this, or at least
not by default. This was a change in the expected norm and the cause of
quite a bit of logs getting dropped and not being noticed until the most
in-opportune time. Before journald writing to syslogd was reliable, you
could do so on any unix system and your log entry would get recorded,
now it isn't.
