To the operator of the 'nixtra.com' network if you are a participant of
this list, or someone here is affiliated with or knows the
owner/operator of this network please inform them of the following:
Your SPF record is extremely broken and results in a breach of the
maximum recursive level as is recommended by the SPFv1 RFC Draft (20
levels).
There are multiple problems with the nixtra.com SPF record.
#1) nixtra.com 'includes' its self
#2) nixtra.com 'includes' nixtra.net which publishes and identical
record to that of nixtra.com.
If you were not already aware this will cause a parse to fail by the
repetitive inclusion of the same domains in addition to likely causing a
substantial delay on anyone receiving mail often from your network.
Please make use of the 'SPF record test page' available freely at
http://spftools.net. An example test can be viewed by using the
following URL:
http://spftools.net/check.php?action=spfcheck&ipv4=10.0.0.2&helo=spftools.net&sender=test%40nixtra.com#result
Alternatively you can make use of the 'SPF Query Tool' binary (spfqtool)
found within the libSPF library available @ http://libSPF.org or the
query tools available in the alternate SPF implementations available
from http://spf.pobox.com in the files/downloads section.
