Now, maybe I'm blind, but I don't see that requirement in RFC 2821 or 5321. And Postfix's SMTP client's default behaviour is: $ postconf -d smtp_always_send_ehlo mail_version smtp_always_send_ehlo = yes mail_version = 2.5.5 I think an initial greeting of 220 fully.qualified.hostname is pretty common this days - especially with so called "anti spam, anti malware" appliances.
