Oh German has that too! They add an asterisk and the female postfix. So Künstler (male artists) and Künstlerinnen (female artists) becomes Künstler*innen to include at least 2 genders (I don't know if this would include non-binary artists too, as again, not a native speaker)

That is how long Postfix holds deferred mail by default before it gives up and bounces it. A blocklist listing you clear on day six does not bring that mail back, and the default config sends the user no warning while the clock runs.

MTA-STS Enforced on Paper: Unread for Three Months
DNS said enforce; 24 of Google's 25 TLS reports said 'no policy found'. An unfetchable MTA-STS policy is silently ignored. Here is how my own origin lockdown did exactly that.
