They did not detect the <CR><LF>.<CR><LF> sequence at the end of the

That's because you type one command at a time.
Try:
/etc/postfix/main.cf:
smtp_discard_ehlo_keyword_address_maps = pcre:/etc/postfix/broken_pipelining
/etc/postfix/broken_pipelining:
192.0.1.1 pipelining
That's for sites that announce support for RFC 2920 (SMTP Pipelining),
but that mis-implement it.
