I'm trying out postscreen. No unexpected explosions so far.

Question:

Jun 16 16:38:48 mail-ausfall postfix/postscreen[22745]: PREGREET 20 after 0.52 
from 222.124.4.14: HELO dmx1.bfi0.com??

The client 222.124.4.14 sent "HELO dmx1.bfi0.com??" 0.52s after the
connection was established. But what does the "20" signify?
