I've been greylisting forever, but I've recently switched to early talker, It

if they talk early they do it immediately.
This sounds similar to spamd(8)'s default behavior for never seen before
contacts,
which is to stutter (again the default of one byte per second) for ten seconds,
then proceed to add a GREY entry.
Early talker means you aren't allowed to say anything until you see the
\r\n at the end of the greeting. What I'm doing is basically 0 byte per
second stuttering.
