Milter-greylist

Hello

I want to greylist envelope from address like the following one

martinwbqxmgwlegros@...


with the following  regex directes in greylist.conf

extendedregex
racl greylist from /^[a-z]{4,16}[bcdfghjklmnpqrstvwxz]{6,10}[a-z]{4,16}@[a-z]{4,16}\.icu$/ delay 4h autowhite 10m

I found no line matching this regex :

# grep -i 'delayed for 04:' /var/log/maillog
match nothing



# grep -E '[a-z]{4,16}[bcdfghjklmnpqrstvwxz]{5,10}[a-z]{4,16}@[a-z]{4,16}\.icu' /var/log/maillog
match a lots of lines.

What is wrong with this racl ?

Regards.

PS. milter-greylist is 4.6.2
