• version: the milter protocol version of MTA.
• macros: object containing all macros.
• uniqueID: unique identifier for milter connection.

METHODS

accept(): Accept message completely (accept/reject action)

This will skip to the end of the milter sequence, and recycle back to the state before SMFIC_MAIL. The MTA may, instead, close the connection at that point.

continue(): Accept and keep processing (accept/reject action)

If issued at the end of the milter conversation, functions the same as accept().

discard(): Set discard flag for entire message (accept/reject action)

Note that message processing MAY continue afterwards, but the mail will not be delivered even if accepted with accept().

reject(): Reject command/recipient with a 5xx (accept/reject action)

tempfail(): Reject command/recipient with a 4xx (accept/reject action)

replycode(code, message): Send specific Nxx reply message (accept/reject action)

• code: string with length of 3 characters. see
• message: string

progress(): Progress (asynchronous action)

This is an asynchronous response which is sent to the MTA to reset the communications timer during long operations. The MTA should consume as many of these responses as are sent, waiting for the real response for the issued command.

quarantine(reason): Quarantine message (modification action)

• reason: string This quarantines the message into a holding pool defined by the MTA.

addheader(header, value): Add header (modification action)

• header: string
• value: string

addrcpt(rcpt): Add recipient (modification action)

• rcpt: string email of new recipient

chgheader(header, num, value): Change a header (modification action)

• header: string
• num: number (integer value)
• value: string Change the num'th header of name header to the value value

delrcpt(rcpt): Remove address rcpt from the list of recipients for this mail (modification action)

• rcpt: string

replacebody(chunk): Replace the message body (modification action)

• chunk: string Replace the message body with the chunk. This method may be called multiple times, each call appending to the replacement buffer. End-of-line should be represented by CR-LF ("\r\n").

setsender(sender): Replace the envelope sender address (modification action)

This method provides an implementation to access the mlfi_setsender method added to the libmilter library as part of the mlfi-setsender project
