Section 4.2 says:
In ABNF, server responses are:
Greeting = "220 " (Domain / address-literal) [ SP text ] CRLF
Reply-line = Reply-code [ SP text ] CRLF
This omits the multiline response cases, and it omits the definition of
Reply-code, so it should be corrected to:
Greeting = "220 " (Domain / address-literal) [ SP text ] CRLF
/ "220-" (Domain / address-literal) [ SP text ] CRLF
*( "220-" [ text ] CRLF )
"220" [ SP text ] CRLF
Reply-line = *( Reply-code "-" [ text ] CRLF )
Reply-code [ SP text ] CRLF
Reply-code = %x31-35 %x30-35 %x30-39
