Sending Email - 550 This message was classified as SPAM and may not be delivered

All outgoing email sent from a Farbyte shared hosting or email hosting account is filtered through our SPAM detection systems. Unfortunately, as this system is automated, this may occasionally stop genuine non-SPAM emails. If you receive a message from the email system stating '550 This message was classified as SPAM and may not be delivered', then the SPAM filters have prevented the delivery of your email. You should do the following:


A - Check The Emails Content

Make sure there are no SPAM type words in your email and that any attachments are also free from such content and malware.


B - Ensure Your Email Client SMTP Authentication Is Setup Correctly
