Dears,
Yesterday we have applied deep inspection in our fortigate to inspect inbound emails (SMTPS/IMAPS/POP3S). Fortigate work find and discard all the emails that are infected, but we noticed some of the clear email recived on junck folder.
Our mail server is Exchange 2016.
1-Is there is anything we have to check it in fortigate?
2-Also if there is additional setup that we have to modified in Exchange server?
3-generlay does the encryption and decryption change email packets?
Thanks.
