The milter-8.c file you mention has a lot of information that I was missing, thank you for that!
One important part is missing, milter response codes are categorised as: - "modification" - "accept/reject" - "asynchronous" But these 3 codes are not mentioned anywhere: SMFIR_CONN_FAIL SMFIR_SETSYMLIST SMFIR_SKIP Do you know which category the fall into? Thank you again for the help. PS: this information is important to know, because modification response codes are not the end of the MTA<->milter dialogue, postfix will expect another response/reply.
