I think you're looking for smtp_discard_ehlo_keyword_address_maps if you want to ignore pipelining offered by remote servers. smtpd_discard_ehlo_keyword_address_maps and postscreen_discard_ehlo_keyword_address_maps to not advertise pipelining for incoming email. Only thing is that you'll have to specify ip addresses not domain names, since dns lookups are not available for these maps. John
