Bounce verification

[Vishal6]

Hi ,

Need to enable bounce verification tagging in destination control. However before that need help on below points.

1. Does enabling bounce verification tagging in destination control requires to change Dane support also in destination control. PFB linkhttps://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/215124-best-practice-guide-for-bounce-verificat.html#anc2

2. does enabling bounce verification tagging in destination control rewrite legitimate sender address

3. Does mail from MAILER-DAEMON@domain.com consider as bounce mail if we enable bounce verification tagging in destination control

1. No. DANE is about asking the other domain via DNS lookups how it wants you to set up the TLS conversation.
2. Yes, it tags the Envelope Sender, aka the Return-Path: header
3. It might be bounce mail... read upon how bounce messages are handled in the online help. It depends upon how you have things configured.
