http://bugzilla.opensuse.org/show_bug.cgi?id=1114761 Bug ID: 1114761 Summary: spamassassin spamd writing errors int logfile and not scanning some email Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Minor Priority: P5 - None Component: Other Assignee: bnc-team-screening@forge.provo.novell.com Reporter: pszaban@wne.edu QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0 Build Identifier: Lots of messages like the following are being written into LEAP 15.0 /var/log/messages file by URIDBL.pm (spamassassin-3.4.1-lp150.5.3.x86_64) plugin: 2018-11-02T00:01:11.353456-04:00 XXXX spamd[2641]: Use of uninitialized value $4 in concatenation (.) or string at /usr/lib/perl5/vendor_perl/5.26.1/Mail/SpamAssassin/Plugin/URIDNSBL.pm line 1044. Reproducible: Sometimes Steps to Reproduce: 1.install Leap15.0, postfix and spamassassin 2.configure postfix to use spamassassin 3.start spamd and postfix 4.wait for email to come in via SMTP on port 25 5.examine /var/log/messages to see the error Unfortunately, I have a lot of config changes in postfix's main.cf and master.cf. I don't think it matters, g spamassassin and postfix seems to do the same thing. FYI: I send mail from postfix to spamd with the following lines in postfix's master.cf: smtp inet n - n - - smtpd -o content_filter=spamfilter:dummy . . . spamfilter unix - n n - - pipe flags=Rq user=defang argv=/usr/local/bin/spamfilter.scr -f ${sender} -- ${recipient} where /usr/local/bin/spamfilter.scr contains: #! /bin/bash /usr/bin/spamc --max-size=1500000 | /usr/sbin/sendmail -i "$@" exit $? ...and I start spamd with: /usr/sbin/spamd -d -i 127.0.0.1 -i ::1 -p 783 -x -m 40 -u spamd -r /var/run/spamd.pid --siteconfigpath=/usr/local/etc/mail/spamassassin/ Actual Results: /var/log/messages contains things like: 2018-11-02T00:01:11.353456-04:00 XXXX spamd[2641]: Use of uninitialized value $4 in concatenation (.) or string at /usr/lib/perl5/vendor_perl/5.26.1/Mail/SpamAssassin/Plugin/URIDNSBL.pm line 1044. Expected Results: should not have produced the error message, and should have scanned the message for URI's and looked them up in the DNS blocklists. I google'd the problem and installed the following patch to /usr/lib/perl5/vendor_perl/5.26.1/Mail/SpamAssassin/Plugin/URIDNSBL.pm. The patch *appears* to have solved the problem for me: --- spamassassin/branches/3.4/lib/Mail/SpamAssassin/Plugin/URIDNSBL.pm 2015/04/28 20:36:05 1676616 +++ spamassassin/branches/3.4/lib/Mail/SpamAssassin/Plugin/URIDNSBL.pm 2015/08/04 23:16:38 1694126 @@ -942,9 +942,8 @@ next unless (defined($str) && defined($dom)); dbg("uridnsbl: got($j) NS for $dom: $str"); - if ($str =~ /IN\s+NS\s+(\S+)/) { - my $nsmatch = lc $1; - $nsmatch =~ s/\.$//; + if ($rr->type eq 'NS') { + my $nsmatch = lc $rr->nsdname; # available since at least Net::DNS 0.14 my $nsrhblstr = $nsmatch; my $fullnsrhblstr = $nsmatch; @@ -1025,9 +1024,9 @@ } dbg("uridnsbl: complete_a_lookup got(%d) A for %s: %s", $j,$hname,$str); - local $1; - if ($str =~ /IN\s+A\s+(\S+)/) { - $self->lookup_dnsbl_for_ip($pms, $ent->{obj}, $1); + if ($rr->type eq 'A') { + my $ip_address = $rr->rdatastr; + $self->lookup_dnsbl_for_ip($pms, $ent->{obj}, $ip_address); } } } I'm reluctant to make many changes to the system to perform testing for fear of losing email. I mostly wanted to make you aware of the issue, and a potential solution to save someone else from having to go through what I recently went through to fix this. -- You are receiving this mail because: You are on the CC list for the bug.
