SPF1 and 2 Help needed! Please Review
We Need help Fast!

We have recently changed domains and decided to update our SPF and
Sender ID records.

Our first question is our syntax which is shown below. Our SPF record
passes perfectly at openspf.org although we would still like an expert
to check it.

Second question is could publishing the Sender ID or SPF2 record below
be hurting us?

Should me modify it or remove [the spf2] record all together? We have
heard mixed opinions because we use a distributed list server
environment and headers are below. One rumor we heard is that the PRA
check in Sender ID could actually provide false positives and thus
really hurt us as we publish several B2B electronic newsletters daily.

domain: verticalmailcorp.com

Published SPF record: v=spf1 ip4:4.71.172.57 a mx ptr
a:gothamlistserver.com ~all

Published Sender ID Record: spf2.0/pra a mx IP4:4.71.172.57 -all

We sent our regular list of about 300K today which we normally send
daily and noticed lower opens and clicks than avaerage and hoping that
an incorrectly spf2 record did not cause this!

Also > our ESP recently changed our header configuration in that instead
of the headers showing the Return-path of bounces@verticalmailcorp.com
to mcgtitan@gothamlistserver.com same for the envelope-from which is
now showing as well.

This has us majorly concerned for both deliverability and authentication
purposes and was one of the main reasons we modded our SPF records.
Clarification is needed asap on this issue

>Published SPF record: v=spf1 ip4:4.71.172.57 a mx ptr a:gothamlistserver.com ~all

first question why make it so hard for the receivers to read your spf?

ok so this equates to
v=spf1 ip4:4.71.172.57 (a = ip4:4.71.172.57 so same damn ip but you cost us one more dns lookup) (mx = ip4:4.71.172.57 but costs us 2 more dns lookups) (ptr = minimum 2 more dns lookups but only uou know how many ptr records point at *.verticalmailcorp.com either way just list the ips and save us the ambiguity and lookups) (a:gothamlistserver.com = ip4:69.67.53.38 and is fine unless the server belongs to you, in which case it isn't going to move ip without you knowing to update the spf first) -all

so the above could be 3 dns lookups cheaper for receivers as (also the more expensive tests last ALWAYS)
v=spf1 ip4:4.71.172.57 a:gothamlistserver.com ptr ~all
or four cheaper if you control the domain gothamlistserver.com or know it will not move
v=spf1 ip4:4.71.172.57 ip4:69.67.53.38 ptr ~all

and ptr is always expensive and silly when you know what ips have FQRDNS as *.verticalmailcorp.com just add the ip's of those that will send mail instead and save receivers looking up every spammer to check if they are *.verticalmailcorp.com

>Published Sender ID Record: spf2.0/pra a mx IP4:4.71.172.57 -all

even though were not supposed to touch senderID as its dumb and bad and no receivers should use it, yes the above can hurt you in two ways
A it will break all forwarders even those doing SRS
B it will break all mail going trough mailinglists or other systems that change the envelope but don't mess with the from: address
C it effectively tells all idiots runing senderID to ignore your SPF record and accept forged envelopes from anywhere (just check the From: )
(obviously only the above for recievers stupid enough to use senderID)

if you use senderID (and everyone should till no receivers are anymore, you should at a minimum equal your SPF policy
in your case
spf2.0/mfrom ip4:4.71.172.57 a:gothamlistserver.com ptr ~all
(ie an spf2.0/mfrom that exactly matches your SPF)
and additionally
spf2.0/pra ip4:4.71.172.57 a:gothamlistserver.com ptr ?all
(ie from: is positive legit if from YOU but also neutral if from forwarders and mailinglists)

>We sent our regular list of about 300K today which we normally send daily and noticed lower opens and clicks than avaerage and hoping that an incorrectly spf2 record did not cause this!

it would if any of your receivers forward mail to say hotmail or other idiots checking senderID as they would be spambucketed at best

>Also > our ESP recently changed our header configuration in that instead of the headers showing the Return-path of bounces@verticalmailcorp.com to mcgtitan@gothamlistserver.com same for the envelope-from

envelope from ONLY
(return path is only added by the last server when the mail arrives to show what the envelope from is)
IF above is true then its only the SPF record of gothamlistserver.com that matters not yours as yours isn't used in the one field that SPF checks.
and if so that will be an issue as they have no SPF

> which is now showing as well.
>
>This has us majorly concerned for both deliverability and authentication purposes and was one of the main reasons we modded our SPF records. Clarification is needed asap on this issue

clarified you spf will never be checked if their domain is used in the envelope, their SPF (none) is all that will be seen
their spf2.0/mfrom (none) also will only be seen
your spf2.0/pra will however be checked (assuming your address in from: and no sender: header supercedes it

the below is pretty much useless as it shows not all the received headers (like which ip hostgator used to send from etc)
but ity does show your SPF is irrelevant to the authenticity of this mail as it doesn't claim to be envelope-from you

Re: SPF1 and 2 Help needed! Please Review [ In reply to ]
Alan,

Awesome explanation and I totally follow you. I also agree with you on
the PTR > please confirm in my case if you really think I need it.

Our ip's change almost never. Is it possible these extra lookups
caused a significant the slowdown today?

Just to confirm our best bet;

v=spf1 ip4:4.71.172.57 ip4:69.67.53.38 ~all

spf2.0/mfrom ip4:4.71.172.57 ip4:69.67.53.38 ~all

spf2.0/pra ip4:4.71.172.57 ip4:69.67.53.38 ?all

i really doubt it but only you know what (if any) other machines are authorised to send email as you

>Our ip's change almost never. Is it possible these extra lookups caused a significant the slowdown today?

not if the mail wasn't from your domain as said on the example sent the domain was gothamlistserver.com
so your SPF wouldn't effect anything

their lack of SPF might have though

yes (if resuming sending envelope-from your domain) if not get them to publish SPF would be worth it

as for the senderID please do not refer to it as spf v2 as it IS NOT RELATED TO SPF
sender ID is entirely an attempt by Microsoft to confuse and mis-use/break SPF for purposes unintented
the only reason publishing a senderID is needed is because without one senderID using idiots will mis-use your spf record as a senderID record and block mail your policy did not intend to block

why I always say end spf2.0/pra records ?all while v=spf1 ether -all or ~all depending on YOUR policy

as far as forwarders, the receivers need to deal with enabling white listing of forwarders in the design of their MTA's I know I ensure all systems I setup do, and all users either whitelist their forwarders or loose mail

yes get them to send a list of all the ips that they send mail from with *@gothamlistserver.com in the envelope sender

and i'll give them the syntax

additionally both you and them (and anyone else using SPF) should also setup an SPF record for each servername that is used in an smtp HELO/EHLO

BTW this mail i am replying to came from
gateway01.websitewelcome.com (gateway01.websitewelcome.com [69.41.242.19]

before it got to listbox so i suspect you have not listed all your own sending ips in your own SPF record

you seem to send via a company called hostgator, so please ask them for a full list of what ip's you send from
or repeatedly mail yourself on a freemail like gmail till you are confident you have built your own list, as at the moment i suspect you don't actually have a working SPF as you don't actually have a complete list of the IP's you send from

send one test to myself directly and i'll have a clear look minus all the extra stuff the listserver adds
