Yes, version 1.97 will do:
my ($result, $smtp_comment, $header_comment, $spf_record) = $query->result();
if ($result eq "unknown" and not $spf_record) { # record does not exist }
if ($result eq "unknown" and $spf_record) { # record does exist,
resolution = unknown }
Have you put any thought toward my idea for the RFC to encode sender
helo, envelope sender, current IP, and matching mechanism into the
comment of Received-SPF in a well-defined way?
header = 'Received-SPF:' result [ FWS '(' [FWS] comment [FWS] ')' ] CRLF
FWS = [*WSP CRLF] 1*WSP
result = 'pass' / 'fail' / 'error' / 'unknown'
/ unknown-declarations
unknown-declarations = 'unknown' *( FWS declaration )
comment = 'h=' smtp-sender-helo FWS 'e=' envelope-sender
FWS 'ip=' current-ip FWS 'm=' match-mechanism
[ FWS 'v=' version-string ] [ FWS comment-string ]
smtp-sender-helo = dot-atom-text
;dot-atom-text is defined in RFC 2822 section 3.2.4
;hostname given by SMTP client at HELO or EHLO command
envelope-sender = dot-atom-text '@' dot-atom-text
;dot-atom-text is defined in RFC 2822 section 3.2.4
;reverse-path given by SMTP client at MAIL FROM command
current-domain = ( IPV4Address / IPV6Address )
;IP address of current SMTP client
IPV4Address = 1*3DIGIT 3( '.' 1*3DIGIT )
IPV6Address = *4HEXDIG 7( ':' *4HEXDIG )
match-mechanism = mechanism / 'none'
;mechanism format specified in section 3.2
;MUST be the mechanism (and argument) part of the SPF record
; which was matched to cause the result, copied exactly from
; the actual SPF record.
;MUST be 'none' if no match was made for any reason
; (ie, error, no SPF information given)
version-string = 1*DIGIT *( '.' 1*DIGIT )
;The SPF version from the SPF record.
; I don't know if this is useful, but we can include it, so why not.
comment-string = *( ccontent [FWS] )
;ccontent is defined in RFC 2822 section 3.2.3
;SHOULD include further information not already provided
; (ie, description of error message in the case of errors)
;MAY include a human-readable explanation of why the current result
; was decided
