Several domains, one webserver/mailserver, same IP Address

Dear sirs:

1) I have a webserver/mail server that runs on a single IP address.

2) The domain is compatibleweb.com (mail.compatibleweb.com)

3) I have some other domains on that web server such as mujer-nueva.com and
amorpostales.com

I have not been able to figure out how to create the right SPF records for
these domains. I want to be able to tell other webservers around the world
that mail from my domains comes from mail.compatibleweb.com (ip 66.235.180.161).

I've tried numerous variations to no avail and my messages end up in hotmail's
spam folder even though I am not on any blacklist. Please advise.

Respectfully,

Jeff

You should use the tests at http://www.kitterman.com/spf/validate.html
to check your prospective records.

From a glance at compatibleweb.com, I think you simply have the wrong
prefix

v-spf1 ip4:66.235.180.161 -all

You want

v=spf1 ip4:66.235.180.161 -all

(note the '=').

Since SPF leverages generic TXT records, if you don't have the right
initial sequence, this record is treated as just any old text. But
don't just assume _not passing_ SPF is why Hotmail is sinking your
mail. It's not that you are failing SPF, you just have, in effect, no
SPF record. Yes, passing might help tip the balance. But also make
sure you pass the standard EHLO-PTR-A "DNS roundtrip" for outgoing
mail, etc....

agreed this is the likely first cause but feel free to send me an email offlist from/via your server so i can show/tell you about any other
PTR>A>IP
HELO>IP
or HELO>SPF>FAIL
issues that my eyes see by looking through headers

as your mail to the list came from dsl-189-175-253-95-dyn.prod-infinitum.com.mx which is neither your server as mentioned or a system most would ever consider anything but spammy

{dsl & dyn in name automatically == bot-spam to most as few accept incoming connections from non-servers}
