Mails are getting into spam within the same domain.
I have some users, for example email@example.com and firstname.lastname@example.org, the problem is when a mail is sent by email@example.com to firstname.lastname@example.org, the email is in the junk of email@example.com in Zimbra Web Client. We are not getting this issue when mails are sent from the same ISP, where the mail server is hosted. We are facing this problem with other ISPs'.
We have posted the FULL HEADERS of the emails also. Below is the FULL HEADER I have included:
