Hello I been facing problem sending emails to specific domain such as @himalayanjava.com @ levoltaireomaha.com

 

I have to reach out to people on daily basis to those domain users. I do not have problem receiving emails but every time I try to send email I get error

XXXXX@himalayanjava.com INVALID ADDRESS, ERROR_CODE :550, ERROR_CODE :SPF :74.201.84.163 is not allowed to send mail from aaptbusinesshouse.com

 

Could you please provide me with workaround.
