I have a dedicated server with a survey system running on a subdomain. The parent domain is hosted on another server. I send email via google apps.
Reverse DNS is correct.
Without SPF og DKIM, the very smart '[email protected]' returns a spamassasin score of ca. 0.
But with a passing SPF record and this summary
SPF check: pass
DomainKeys check: neutral
DKIM check: neutral
Sender-ID check: pass
SpamAssassin check: ham
I get a quite high spamassasin score of ca. 3 - due to the header being very big:
pts rule name description
---- ---------------------- --------------------------------------------------
3.1 SINGLE_HEADER_2K A single header contains 2K-3K characters
-0.7 RCVD_IN_DNSWL_LOW RBL: Sender listed at http://www.dnswl.org/, low
trust
So my question is: It seems from this that I should delete the spf record? since a large header is deemed worse then a valid spf?
Or is it my spf which is wrong?
v=spf1 a mx ptr ip4:xxx.xx.xxx.xx mx include:_spf.google.com ip4:yy.yy.yy.yyy ~all
xxx IP is for the server with the tld yyy IP is the server where the subdomain is hosted.
Below a part of the header:

Again I have crossed out my own IP's and the rest i guess is googles?
What should I do now? Should I delete the spf record, or can I change it somehow to get a smalle header, that still works?
