SMTP Error (550)
I have been getting "SMTP Error (550): Failed to set sender "sales@racewatches.com" (Administrative prohibition) for days now every time time I try to send, forward or reply to an email
Is there any solution to this problem?

Hello,
Can you go ahead and try once more? I have updated the TXT SPF record for your domain which should allow it to begin working properly.
