Gmail marking email from Sentora as SPAM

[5050]

Hi,
There is at last a fatal error that disable our spf : there are 2 spf record, but only one is allowed !
They are :

Code:

v=spf1 a mx ip6:2001:41d0:52:a00::dd6 include:sentora.org ~all
v=spf1 mx a a:mail1.supared.com include:spf.mailjet.com ?all

The second was setup by me from record infos provided by Bobby, I do not know from where come the first but it cannot remains !

I tryed to merge them both in :

Code:

v=spf1 mx a a:mail1.supared.com include:spf.mailjet.com include:sentora.org ?all

but it created an error (reported by http://www.kitterman.com/spf/validate.html) :
->  Results - PermError SPF Permanent Error: include has trivial recursion: includeentora.org

=> I think that entries "a" and "sentora.org" are redondant : both resolves to same IP
=> I also think that both entries "mx" and "a:mail1.supared.com" are redondant because sentora.org MX is setup to mail1.supared.com. May be the second can be removed ?
=> I also tried to add entry ip6:2001:41d0:52:a00::dd6, and turned to softfail all instead of netural.

The (alone) record is now :

Code:

v=spf1 mx a ip6:2001:41d0:52:a00::dd6 a:mail1.supared.com include:spf.mailjet.com ~all

And now waiting a few hour until record proagation before checking again.

But as I am not at all a specialist in spf record, any help or comment will be welcome.
