In the access(5) man page, it is either explicitly stated or else easily inferred what XXX response value will be sent back to the SMTP client for each of the possible values listed in the ACCEPT ACTIONS and REJECT ACTIONS sections.
What XXX response values will be sent back to the SMTP client for each of the various possible lookup result values listed in the OTHER ACTIONS section? I am most particularly interested in obtaining the answer to this question for the PREPEND and WARN values, but would really like to know the answer for all of the various values listed within the OTHER ACTIONS section. Thanks in advance for any assistance.
