I am not very familiar with SPF records so I need a bit of help setting up my SPF record correctly.
Below is a record I created using online tutorials
v=spf1 a mx ip4:192.186.236.104 include:_spf.google.com include:bmsend.com include:postbox.pidatacenters.com ~all
when i check in http://mxtoolbox.com/SuperTool.aspx?action=spf%3apidatacenters.com%3a192.186.236.104&run=toolpage#
it shows everything is right
fraudmarc.com/spf-record-check/
in this website it shows an error like this
Give me the solutions
Thanks in advance.
A few things wrong here. The definitive SPF checker is Scott Kitterman's. It finds this error:
PermError SPF Permanent Error: Unknown mechanism found: postbox.pidatacenters.com
It's not clear why this is presented as this particular error because the syntax itself is valid, but you have a recursive definition - your SPF includes postbox.pidatacenters.com, but the SPF for that domain includes itself, which makes no sense. It also contains the google SPF, so you don't need to include that again.
I suggest you set your SPF records to these. For pidatacenters.com:
v=spf1 ip4:192.186.236.104 mx include:bmsend.com include:postbox.pidatacenters.com ~all
you don't need the a clause in there because it resolves to the same IP as you already listed. It's polite to put ip clauses first as they are fastest to resolve for receivers, as they do not require DNS lookups.
For postbox.pidatacenters.com:
v=spf1 include:_spf.google.com ~all
