For the email to land in the Gmail inbox, information technology should originate from a valid mail server IP address. The mail server should be authorized to handle mails on behalf of the domain. Again, the IP address should accept a good mail reputation score.

If the reputation score of post server is very bad, Gmail can easily mark the mail service as spam.

Only, in this instance, the domain had perfect DNS settings and our Defended Engineers confirmed the with DNS lookup tools as well.

Unfortunately, analyzing the email logs in the server, we could run across that there was a form in 1 of the websites that was sending mails to a huge gmail account list. Unfortunately, recipients were marking mails every bit Spam in their Gmail. And, this caused the Gmail to mark mails every bit Spam and movement them to the binder.
