[Bug 6769] New: dns_available described in Mail::SpamAssassin::Conf could lead to disable dns test and cause DKIM, SPF and ASN to fail

https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6769

             Bug #: 6769
           Summary: dns_available described in Mail::SpamAssassin::Conf
                    could lead to disable dns test and cause DKIM, SPF and
                    ASN to fail
           Product: Spamassassin
           Version: 3.3 SVN branch
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Documentation
        AssignedTo: dev@spamassassin.apache.org
        ReportedBy: xtrade@matik.com.br
    Classification: Unclassified


excerpt from Mail::SpamAssassin::Conf:     The problem is that it can introduce
some delay if your network connection is down, and in some cases it can wrongly
guess that DNS is unavailable because the test connections failed. SpamAssassin
includes a default set of 13 servers, among which 3 are picked randomly. 


this text explains "13 servers, among which 3 are picked" 

and then offers

You can however specify your own list by specifying

...

it should be better stating clearly that it queries DOMAIN names for their NS
Servers and not the Servers

if some specifies a list of servers for "dns_available test: host1 host2" then
significant tests are disabled without good explanation, even -D --lint do not
return a good value

with wrong settings here, for example dkim always return T_DKIM_INVALID,
SPF_PASS or any SPF report does not appear at all as well as no ASN report is
showing up

I suggest changing at least

You can however specify your own list by specifying

into 

You can however specify your own list by specifying one or more domain names

and

and in some cases it can wrongly guess that DNS is unavailable because the test
connections failed. SpamAssassin includes a default set of 13 servers, among
which 3 are picked randomly.

and in some cases it can wrongly guess that DNS is unavailable because the test
connections failed, what cause disabling several dns dependent tests.
SpamAssassin includes an internal list, among which 3 DOMAINS are picked
randomly for checking their DNS servers.


thank's
