I've been doing some tests of my postfix server and sometimes when I connect, I get *two* ESMTP banners, one that has a hyphen (-) after the 220, and one that doesn't. Other connections, I only get one banner:
that is the postscreen banner: http://www.postfix.org/POSTSCREEN_README.html If the connecting machine's IP is cached, the banner is not shown. Florian
