Ok, I've been reading this forum for awhile and after realizing that
dnsstuff.com has an SPF test (man I missed that one) in addition to the one
on the official SPF web site, I did the test and it failed me yesterday even
though the other test on the SPF site passed me. I had read something about
the SPF wizard leaving quotes around the TXT string being a bad thing, so I
removed the quotes encapsulating my SPF TXT record and tested on DNS stuff
today. Overall, it passed. But there is one failure in the series of tests
it appeared to do that I have a question about:
-----------------------------------------------------
SPF lookup of sender fdickey@v-sources.com from IP 64.139.78.162:
SPF string used: v=spf1 ip4:64.139.78.162 mx a:mail.v-sources.com
mx:mail.v-sources.com -all.
Processing SPF string: v=spf1 ip4:64.139.78.162 mx a:mail.v-sources.com
mx:mail.v-sources.com -all.
Testing 'ip4:64.139.78.162' on IP=64.139.78.162, target domain
64.139.78.162, CIDR 32, default=PASS. MATCH!
Testing 'mx' on IP=64.139.78.162, target domain v-sources.com, CIDR 32,
default=PASS. Testing 'a:mail.v-sources.com' on IP=64.139.78.162, target
domain mail.v-sources.com, CIDR 32, default=PASS. Testing
'mx:mail.v-sources.com' on IP=64.139.78.162, target domain
mail.v-sources.com, CIDR 32, default=PASS. Testing 'all' on
IP=64.139.78.162, target domain v-sources.com, CIDR 32, default=FAIL.
<<<---this is the one ????
Result: PASS
Known Issues:
None.
-------------------------------------
In this test, everything appears to pass except for the last test "Testing
'all'". I am assuming that this is because I have the -all at the end of my
TXT record indicating that no other servers are allowed to send email that
is not specified directly in the TXT record. In that case, that's exactly
what I would want to fail. Is this a correct assumption or do I still need
to resolve an issue with my SPF record?
My SPF record appears as follows:
"v=spf1 ip4:64.139.78.162 mx a:mail.v-sources.com mx:mail.v-sources.com
-all"
It's strange that DNSstuff failed me yesterday when the registration site
for SPF passed me a few weeks ago. LOL.
BTW, I'm aware that my reverse DNS resolves back to the hostname assigned by
my ISP. In the future, will this matter? Will the reverse DNS hostname be
scrutinized to resolve back to the same domain as the forward DNS record? I
wouldn't think so, since the reverse hostname record for my ISP will
eventually lead back to me through their records if someone really wanted to
find out who was sending what, but I could be wrong. Would it be best
practice to update the reverse record or does it matter?
Thanks in advance for anyone's input.
