Thank you for your suggestions.
Here is one additional thing I want to tell you
emails being sent from leartclub.com has HELO addresses cpanel.channelof.com
means we are using that as SMTP server
based on above any other changes required (because I heard that receivers
inbound mail server will check HELO and recerse DNS of that)
Thanks

No one here can tell you whether the SPF policy is correct since none of us have
knowledge of your network infrastructure. The best we can do is tell you whether
the syntax of the policy is correct and to confirm with you what has been
published and whether that is in fact what you intended to publish.
When I look up the policy for leartclub.com I get the following.
leartclub.com. IN TXT "v=spf1 ip4:174.37.103.245 a mx ~all"
This tells us that the only server allowed to send mail on behalf of
'leartclub.com' is at the IP address 174.37.103.245. If this is correct from the
knowledge you have about your network set up then your policy is correct.
You should be aware that you policy statement has some un-needed redundancy that
are an artifact of using the wizard to determine the policy.
The 'a' and 'mx' point to the same IP address and are therefore not needed and
only serve to generate un-needed extra DNS lookups and by extension un-needed
traffic. You can and should remove those to simplify the policy to look like
this.
v=spf1 ip4:174.37.103.245 ~all
Also, once you are satisfied that the policy you've published is correct and
also, and this is very important, that all your email users are aware that they
are now restricted to only relaying mail fthrough the approved server and you
have put in place the mechanisms to allow that to happen then you can and should
change '~all' to '-all'.
