As the information will be public.. why not give real information as it
will be ALOT easiler for someone to help you.

Thanks

Actually, this makes it a lot harder to help you.

The information is public so you may as well use real domain names an
IP addresses.

no it dosn't

thats not what a subdomain is
a subdomain of say
gothic.ie is www.gothic.ie or dominion.gothic.ie

if site b.com redirects to a page on a.com/page then {a its irrelevent to what SPF is about which is EMAIL} {b see a}

yes thats dumb no ptr means no right to send mail anywhere or be connected to the internet

this will not cause any blacklisting {yahoo don't even use/check SPF}

you cannot legally use a CNAME within a zone with MX or A records a cname is exclusive and means "do not read my records see these records instesd"

the ips PTR can be in any of the 4 zones you have ownership of {whether registered with "HOST.com" or GoDaddy}
as long as you set the same name up with equivalent ip {and don't use the top-level domain, a PTR is always hostname.domain.com anything else is considered bad admin thus low reputation of trust}

this all seems pretty spammy to me
A why no real details
B why needing to send large volumes from 3 different domains

so i'm outta here till some other evidence is shown {like the real ip's and the real domains} as only a spammer would want to hide who they are

Two people have already said it would be easier if I use real URLs and
IPs. So I've edited my request. (Cryptic version below)

====

I am new to DNS and SPF but I think I almost understand it. Could you
tell me whether I have this right?

1. I have 3 domains (econcurrent.com, angelusdevice.com, tvigate.com)
hosted at jumplaunch.com. So all have the same IP, 76.74.223.179.
jumplaunch.com has its DNS server.

2. angelusdevice.com & tvigate.com are subdomains of econcurrent.com,
(i.e., angelusdevice.com => econcurrent.com/angelus & tvigate.com =>
econcurrent.com/tvi)

3. jumplaunch.com got blacklisted by yahoo.com. That's been fixed. They
had no PTR or SPF records in DNS, only A, CNAME and MX I had to learn
this stuff and tell them what they had to learn and do to keep it clean.

4. jumplaunch.com also has a mail quota too low for my mailing list.

5. So I

1) got domain dependablemail.net FROM GoDaddy,
2) switched to charter.com to get static IP 71.8.241.2.
3) set dependablemail.net to point to 71.8.241.2
3) got an SMTP server to run on my WinXP system (ughh).

6. I want to send mail *for* econcurrent.com, angelusdevice.com,
tvigate.com *from* HOST jumplaunch.com and dependablemail.net. Are
these SPF records right?

econcurrent.com IN TXT "v=spf1 ip4:71.8.241.2 ip4:76.74.223.179 -all"
angelusdevice.com IN TXT "v=spf1 ip4:71.8.241.2 ip4:76.74.223.179 -all"
tvigate.com IN TXT "v=spf1 ip4:71.8.241.2 ip4:76.74.223.179 -all"

7. This goes in both GoDaddy's DNS (for dependablemail.net) and HOST
jumplaunch.com's DNS (for econcurrent.com, angelusdevice.com,
tvigate.com), right?

8. I must put a PTR record in ISP charter.com's DNS (for
dependablemail.net) and HOST jumplaunch.com's DNS (for econcurrent.com,
angelusdevice.com, tvigate.com), right?

Thank you.

I don't understand that. I guess I used the wrong terminology, I've
never seen it clearly defined. Jump:aunch calls it an AddOn

It's three very different businesses. Loan modifications, an advanced EM
biofeedback device and a travel club matrix.

sounds even worse now who would join a confirmed opt in mailinglist on those {in enough numbers for their to be a large volume}

{any other type of mailinglist IS spam}
{spam != illegal, spam is any recipient who has not explicitly consented to mail from that particular list}

Everyone had opted-in. There is the required easy-to-see one-click

Now, now.. Spammers are entitled to use SPF just like anybody else. It's
better if they do, because it makes them easier to block them. >:D


Thomas, with all the back and forth, did you get all your questions
answered?

I've actually seen an increase in spam from non-forged addresses lately.

I think SPF might be starting to bite the bad guys :-)

I'm noticing the same thing. This is good!

Now does anyone know of a public Real-time Block List (RBL) based on
SPF data (a bad guys list) that one could subscribe to. This sounds
like something Spamhaus should add to their list of excellent services.
