Some emails do not send and I get this error message:
An error occurred while sending mail. The mail server responded: We're sorry, but we can't send your email. Either the subject matter, a link, or an attachment potentially contains spam, or phishing or malware. Please check or edit your message and try sending it again. (6-1-3-2) ID (6139417C375D4C3E). Please check the message and try again.
I have tried copying and pasting the body text into different emails and email clients, same problem, but if I try to send to my Gmail account as a test it works OK.
Is it perhaps associated with the people I am sending to?
