Hi all,
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: $ nc -v server.example.net 25 Connection to server.example.net (10.0.0.1) 25 port [tcp/smtp] succeeded! 220-server.example.net ESMTP (spam is not appreciated) 220 server.example.net ESMTP (spam is not appreciated) quit 221 2.0.0 Bye root@mon02-mtl:~# nc -v server.example.net 25 Connection to server.example.net (10.0.0.1) 25 port [tcp/smtp] succeeded! 220 server.example.net ESMTP (spam is not appreciated) quit 221 2.0.0 Bye Can someone explain what the two banners mean, and why they happen sometimes, and are slightly different? thanks! Micah
