spf error 550 5.1.1 SPF IB508

Hi, I'm new to sophos, I'm currently setting up an advanced mail service account.
and I'm having some problems when receiving emails, some are rejected and I get an email from sophos

failure reason: : host said: 550 5.1.1 198.154.181.158 is not allowed to send from per its SPF Record. Please inspect your SPF settings, and try again. IB508
when removing the mx records the email is received correctly but when putting them in, the sender gets this message

Does anyone have an idea of ​​what the problem is?
