Bug ID: 7777
Summary: askdns problem with multi-valued resource records
Product: Spamassassin
Version: 3.4.2
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Plugins
Assignee: dev@spamassassin.apache.org
Reporter: sa-...@lrz.de
Target Milestone: Undefined
askdns only works on the first resource record it receives even if it is a
multi-value RR.
Example:
dig +short txt lrz.de
"google-site-verification=aery99S4-qQNyQyHH2_P3UlwnXrfYgKa-BHwwKDRY1w"
"v=spf1 redirect=_spf.mail.lrz.de"
echo 'From: t...@lrz.de'|spamassassin -D all --cf 'askdns LRZ_ASKDNS
_AUTHORDOMAIN_ TXT /.+/' 2>&1|grep LRZ_ASKDNS|grep listed
Dec 11 16:13:49.624 [109500] dbg: askdns: domain "lrz.de" listed (LRZ_ASKDNS):
google-site-verification=aery99S4-qQNyQyHH2_P3UlwnXrfYgKa-BHwwKDRY1w
or
echo 'From: t...@lrz.de'|spamassassin -D all --cf 'askdns LRZ_ASKDNS
_AUTHORDOMAIN_ TXT /.+/' 2>&1|grep LRZ_ASKDNS|grep listed
Dec 11 16:14:05.619 [109689] dbg: askdns: domain "lrz.de" listed (LRZ_ASKDNS):
v=spf1 redirect=_spf.mail.lrz.de
It never checks both records.
Deleting the line
$pms->{askdns_map_dnskey_to_rules}{$dnskey}[$j++] = undef;
solves the problem for me:
echo 'From: t...@lrz.de'|spamassassin -D all --cf 'askdns LRZ_ASKDNS
_AUTHORDOMAIN_ TXT /.+/' 2>&1|grep LRZ_ASKDNS|grep listed
