New and Changed Features
This section lists the changes in behavior of Sky ATP features and in Junos OS Release 15.1X49-D120 for Sky ATP.
IMAP E-Mail Attachments
Starting in Junos OS Release 15.1X49-D120, e-mail management for IMAP lets enrolled SRX Series devices transparently submit potentially malicious e-mail attachments to the cloud for inspection. Once an attachment is evaluated, Sky ATP assigns the file a threat score from 0 through 10 with 10 being the most malicious. In addition, e-mails are checked against administrator-configured blacklists and whitelists. If an e-mail matches the blacklist, it is considered to be malicious and is handled the same way as an e-mail with a malicious attachment.
Please refer to the Supported Platforms Guide 
for IMAP support on various SRX Series
devices.
