I tried sending a mail with html tags and it worked fine. I do this when users try to get a new password when they have forgotten their own. I use recaptcha to prevent spam and it works all fine.
But when i recently made a contact form which sent the mail with jquery ajax, i get this message from hotmail:
"This message looks very suspicious to our SmartScreen filters, so we've blocked attachments, pictures, and links for your safety."
I get this message even if i just send plain text with <br> tags.
Any idea what the reason could be? I sent the same message using regular form with recaptcha and it worked. But sending it with ajax result in this.
