IMAP-Proxy: APT Blocker
If you have purchased and enabled APT Blocker on your Firebox, you can enable APT Blocker in the IMAP proxy to examine mail traffic for APT malware.
APT Blocker can help protect your network from zero-day attacks sent as email attachments. When APT Blocker is enabled in the IMAP proxy, there can be a brief delay in retrieval of some messages that contain attachments that require analysis. For more information, see About APT Blocker.
APT Blocker is part of the same scan process as Gateway AntiVirus. When you enable APT Blocker in a proxy action, APT Blocker scans content only when content matches a proxy action rule configured with the AV Scan action.
For more information about APT Blocker, see About APT Blocker.
