The AOL.com record is:

v=3Dspf1 ptr:mx.aol.com ?all

that says:

ptr:mx.aol.com - the host that resolves from (and back to) mx.aol.com
?all - this SPF record is meaningless - accept all email

That may boil down to two lookups, e.g. if IP=3D205.188.159.57 find=20
da.mx.aol.com by rDNS and then check that the latter has the same IP.=20
Considering that these lookups are most commonly performed anyway, it=20
may actually cost less than include or redirect.

The "pass" they may obtain that way only serves spam scores.

v=3D3Dspf1 ptr:mx.aol.com ?all

that says:

ptr:mx.aol.com - the host that resolves from (and back to) mx.aol.com
?all - this SPF record is meaningless - accept all email

Worth reading http://www.openspf.org/SPF_Record_Syntax

--=3D20
Please keep list traffic on the list.

That may boil down to two lookups, e.g. if IP=3D3D205.188.159.57 find=3D20
da.mx.aol.com by rDNS and then check that the latter has the same IP.=3D20
Considering that these lookups are most commonly performed anyway, it=3D20
may actually cost less than include or redirect.

The "pass" they may obtain that way only serves spam scores.

Many thanks Rob, and the other members that helped on this. To *help*
ensure that all of my emails go to peoples inbox's, I am looking into the
3 methods of doing this - i.e., SPF, Sender ID and DomainKeys - are there
any others ? The info on the link below, seems to indicate that emails
can break with forwards, when using SPF, but not when using DomainKeys -
is that true ?

First, all three don't "help" mail get delivered, they help
prevent others from using your domain to spam people. A subtle
difference.

The interaction between SPF and forwarding depends on whether
the mail is forwarded or re-sent. See:
http://www.openspf.org/FAQ/Forwarding.

My experience is that small but growing number of ISPs are refusing to
set up auto-forwards for e-mail, due not only to SPF but the probability
of forwarding spam (resulting in the ISP's server being blacklisted).

Not noted on the page you linked to (from 2005) is that DKIM and
DomainKeys are not the same thing, but that's a question for a different
list.

The AOL.com record is:

v=3D3D3Dspf1 ptr:mx.aol.com ?all

that says:

ptr:mx.aol.com - the host that resolves from (and back to) mx.aol.com
?all - this SPF record is meaningless - accept all email

That may boil down to two lookups, e.g. if IP=3D3D3D205.188.159.57 find=3D3=
D20
da.mx.aol.com by rDNS and then check that the latter has the same IP.=3D3D20
Considering that these lookups are most commonly performed anyway, it=3D3D20
may actually cost less than include or redirect.

The "pass" they may obtain that way only serves spam scores.

Many thanks Rob, and the other members that helped on this. To *help*
ensure that all of my emails go to peoples inbox's, I am looking into the
3 methods of doing this - i.e., SPF, Sender ID and DomainKeys - are there
any others ? The info on the link below, seems to indicate that emails
can break with forwards, when using SPF, but not when using DomainKeys -
is that true ?

First, all three don't "help" mail get delivered, they help
prevent others from using your domain to spam people. A subtle
difference.

The interaction between SPF and forwarding depends on whether
the mail is forwarded or re-sent. See:
http://www.openspf.org/FAQ/Forwarding.

My experience is that small but growing number of ISPs are refusing to
set up auto-forwards for e-mail, due not only to SPF but the probability
of forwarding spam (resulting in the ISP's server being blacklisted).

Not noted on the page you linked to (from 2005) is that DKIM and
DomainKeys are not the same thing, but that's a question for a different
list.

The AOL.com record is:

v=3D3D3D3Dspf1 ptr:mx.aol.com ?all

that says:

ptr:mx.aol.com - the host that resolves from (and back to) mx.aol.com
?all - this SPF record is meaningless - accept all email

That may boil down to two lookups, e.g. if IP=3D3D3D3D205.188.159.57 find=
=3D3D3=3D
D20
da.mx.aol.com by rDNS and then check that the latter has the same IP.=3D3D3=
D20
Considering that these lookups are most commonly performed anyway, it=3D3D3=
D20
may actually cost less than include or redirect.

The "pass" they may obtain that way only serves spam scores.

Many thanks Rob, and the other members that helped on this. To *help*
ensure that all of my emails go to peoples inbox's, I am looking into the
3 methods of doing this - i.e., SPF, Sender ID and DomainKeys - are there
any others ? The info on the link below, seems to indicate that emails
can break with forwards, when using SPF, but not when using DomainKeys -
is that true ?

First, all three don't "help" mail get delivered, they help
prevent others from using your domain to spam people. A subtle
difference.

The interaction between SPF and forwarding depends on whether
the mail is forwarded or re-sent. See:
http://www.openspf.org/FAQ/Forwarding.

My experience is that small but growing number of ISPs are refusing to
set up auto-forwards for e-mail, due not only to SPF but the probability
of forwarding spam (resulting in the ISP's server being blacklisted).

Not noted on the page you linked to (from 2005) is that DKIM and
DomainKeys are not the same thing, but that's a question for a different
list.

As covered in the FAQ - SenderID is NOT SPF.

Note that by using ~all you've said (as mentioned at
http://www.openspf.org/SPF_Record_Syntax) to accept, but mark
(SoftFail). If you want mail failing the SPF check to be rejected you
need to:

a) Use "-all"
b) Check SPF records at your MX hosts, configured to reject mail that Fails

To comment on your SPF record we HAVE to know the real domain in
question, it's impossible to help based on false information. Note
that the SPF record should never use RFC1918 addresses, as your
altered record appears to.

Finally, do you send email through Postini, directly to your Exchange
server, or via EasyDNS?

Hi Rob,

Thanks for the reply. I will remove the private range from the SPF
record. Here is the full unedited SPF record:

v=3Dspf1 ip4:192.168.103.0/24 ip4:206.14.210.88 ip4:64.18.0.0/20mx
include:easydns.com ~all

The domain is h5marketing.com.

Inbound email goes through Postini directly to the Exchange server.
Before using Postini I used easydns, so I can remove that portion know I
supose.

So for the new SPF record it seems like this would work for me:
v=3Dspf1 ip4:206.14.210.88 ip4:64.18.0.0/20mx -all

Do you agree?

Thanks,
Ryan

Fails

To comment on your SPF record we HAVE to know the real domain in
question, it's impossible to help based on false information. Note that
the SPF record should never use RFC1918 addresses, as your altered
record appears to.

Finally, do you send email through Postini, directly to your Exchange
server, or via EasyDNS?

SPF is about how you SEND email, not about how you receive it. Your
SPF record should list the IP addresses/ranges from which the domain
SENDS email.

If you are receiving the spam, your mail server needs to check
for SPF on the incoming messages. Your SPF record is not relevant,
unless they are using your domain.

Note Sender ID is not SPF, see the FAQ.

"ip4:64.18.0.0/20mx" needs a space before the MX (if you
published it that way, the entire record is invalid). So you send mail
out using easydns.com mail servers (as well as Postini's)? They use a
lot of servers:

easydns.com. 3600 IN TXT "v=3Dspf1 mx ptr
ip4:205.210.42.0/24 ip4:216.220.40.240/29 ip4:66.207.199.35/32
ip4:64.68.200.0/24 include:myprivacy.ca ptr:opensrs.net

Will SPF prevent the type of SPAM where the spammer has forged my
domains email address? This is confusing to me because SPF prevents
sender forgery, but will it prevent someone sending email to my domain
when they forge my domain address? Maybe SPF is not the right solution
to prevent this?

SPF is about how you SEND email, not about how you receive it. Your SPF
record should list the IP addresses/ranges from which the domain SENDS
email.

Steve,

Yes I am receiving spam on incoming mail and yes they are forging my
domain. I am no longer using easydns for outbound mail, just Postini. I
have Postini's large /20 block included in the SPF record.

It will, when your SPF record says to reject FAILing checks (-all) AND
they check SPF records and honour your record's request.

Then you should remove the "include:easydns.net" from your SPF
record. You only want to list your outgoing mail servers. And when
your are happy with your SPF record
(http://www.kitterman.com/spf/validate.html) then change ~all to -all.

Date: Tue, 25 Aug 2009 17:55:46 +1200

Hello, Can someone be kind enough to double-check this SPF record? My domain
is a-la-carte-australia-tours.com <http://www.a-la-carte-europe-tours.com/>=
and
the SPF record is "v=3Dspf1 include:customer-spf.mxes.net
a:smtp.cotse.net-all" ; I send mail using exclusively either
tuffmail.com or cotse.net email services. Tuffmail's recommendation is to
use include:customer-spf.mxes.net ; so no problem there. All mail sent
through Cotse is via smtp.cotse.net . Test emails sent to GMail validate OK.
The tests on http://www.kitterman.com/spf/validate.html seem to agree with
my record as well. Is that all OK?

Thank you,

Mark Wolk

If it validates, that is about all we can verify. You have to

The AOL.com record is:

v=3D3D3D3D3Dspf1 ptr:mx.aol.com ?all

that says:

ptr:mx.aol.com - the host that resolves from (and back to) mx.aol.com
?all - this SPF record is meaningless - accept all email

That may boil down to two lookups, e.g. if IP=3D3D3D3D3D205.188.159.57 find=
=3D
=3D3D3D3=3D3D
D20
da.mx.aol.com by rDNS and then check that the latter has the same IP.=3D3D3=
D3=3D
D20
Considering that these lookups are most commonly performed anyway, it=3D3D3=
D3=3D
D20
may actually cost less than include or redirect.

The "pass" they may obtain that way only serves spam scores.

Many thanks Rob, and the other members that helped on this. To *help*
ensure that all of my emails go to peoples inbox's, I am looking into the
3 methods of doing this - i.e., SPF, Sender ID and DomainKeys - are there
any others ? The info on the link below, seems to indicate that emails
can break with forwards, when using SPF, but not when using DomainKeys -
is that true ?

First, all three don't "help" mail get delivered, they help
prevent others from using your domain to spam people. A subtle
difference.

The interaction between SPF and forwarding depends on whether
the mail is forwarded or re-sent. See:
http://www.openspf.org/FAQ/Forwarding.

My experience is that small but growing number of ISPs are refusing to
set up auto-forwards for e-mail, due not only to SPF but the probability
of forwarding spam (resulting in the ISP's server being blacklisted).

Not noted on the page you linked to (from 2005) is that DKIM and
DomainKeys are not the same thing, but that's a question for a different
list.

Hello,

Looking for help with SPF, I think I have set it up incorrectly.=3D20

Situation: I'm getting a heavy volume of spam where the From Sender is
the same as the To Sender. I believe SPF should prevent this spam from
getting through.

My Setup: Exchange 2003 SP2 Sender ID Filtering enabled with public
hosted DNS - easydns.com, also using Postini. I have created the
following SPF record: v=3D3Dspf1 ip4:192.168.103.0/24 ip4:206.14.xxx.xxx
ip4:64.18.0.0/20mx include:easydns.com ~all

I edited the public IP of my Exchange server. The /20 block is for
Postini. Can anyone see something I am doing wrong here?=3D20

As covered in the FAQ - SenderID is NOT SPF.

Note that by using ~all you've said (as mentioned at
http://www.openspf.org/SPF_Record_Syntax) to accept, but mark
(SoftFail). If you want mail failing the SPF check to be rejected you
need to:

a) Use "-all"
b) Check SPF records at your MX hosts, configured to reject mail that Fails

To comment on your SPF record we HAVE to know the real domain in
question, it's impossible to help based on false information. Note
that the SPF record should never use RFC1918 addresses, as your
altered record appears to.

Finally, do you send email through Postini, directly to your Exchange
server, or via EasyDNS?

Hi Rob,

Thanks for the reply. I will remove the private range from the SPF
record. Here is the full unedited SPF record:

v=3D3Dspf1 ip4:192.168.103.0/24 ip4:206.14.210.88 ip4:64.18.0.0/20mx
include:easydns.com ~all

The domain is h5marketing.com.

Inbound email goes through Postini directly to the Exchange server.
Before using Postini I used easydns, so I can remove that portion know I
supose.

So for the new SPF record it seems like this would work for me:
v=3D3Dspf1 ip4:206.14.210.88 ip4:64.18.0.0/20mx -all

Do you agree?

Thanks,
Ryan

SPF is about how you SEND email, not about how you receive it. Your
SPF record should list the IP addresses/ranges from which the domain
SENDS email.

Please keep list traffic on the list.

If you are receiving the spam, your mail server needs to check
for SPF on the incoming messages. Your SPF record is not relevant,
unless they are using your domain.

Note Sender ID is not SPF, see the FAQ.

"ip4:64.18.0.0/20mx" needs a space before the MX (if you
published it that way, the entire record is invalid). So you send mail
out using easydns.com mail servers (as well as Postini's)? They use a
lot of servers:

easydns.com. 3600 IN TXT "v=3D3Dspf1 mx ptr
ip4:205.210.42.0/24 ip4:216.220.40.240/29 ip4:66.207.199.35/32
ip4:64.68.200.0/24 include:myprivacy.ca ptr:opensrs.net

Will SPF prevent the type of SPAM where the spammer has forged my
domains email address? This is confusing to me because SPF prevents
sender forgery, but will it prevent someone sending email to my domain
when they forge my domain address? Maybe SPF is not the right solution
to prevent this?

Thanks,

Steve,

Yes I am receiving spam on incoming mail and yes they are forging my
domain. I am no longer using easydns for outbound mail, just Postini. I
have Postini's large /20 block included in the SPF record.

It will, when your SPF record says to reject FAILing checks (-all) AND
they check SPF records and honour your record's request.

Then you should remove the "include:easydns.net" from your SPF
record. You only want to list your outgoing mail servers. And when
your are happy with your SPF record
(http://www.kitterman.com/spf/validate.html) then change ~all to -all.

Hello, Can someone be kind enough to double-check this SPF record? My domain
is a-la-carte-australia-tours.com <http://www.a-la-carte-europe-tours.com/>=
=3D
and
the SPF record is "v=3D3Dspf1 include:customer-spf.mxes.net
a:smtp.cotse.net-all" ; I send mail using exclusively either
tuffmail.com or cotse.net email services. Tuffmail's recommendation is to
use include:customer-spf.mxes.net ; so no problem there. All mail sent
through Cotse is via smtp.cotse.net . Test emails sent to GMail validate OK.
The tests on http://www.kitterman.com/spf/validate.html seem to agree with
my record as well. Is that all OK?

Thank you,

Mark Wolk

If it validates, that is about all we can verify. You have to
determine if it covers all the servers sending outgoing mail for your
