Behavior when modifying headers: Use encoding of message body Behavior for untagged non-ASCII headers: Impose encoding of message body Behavior for mismatched footer or heading encoding: Try both body and footer or heading encodings Behavior when decoding errors found: Disclaimer is displayed as inline content and the message body is added as an attachment.
Choose the operation you want to perform: - SETUP - Configure multi-lingual settings. []> setup
If a header is modified, encode the new header in the same encoding as the message body? (Some MUAs incorrectly handle headers encoded in a different encoding than the body. However, encoding a modified header in the same encoding as the message body may cause certain characters in the modified header to be lost.) [Y]>
If a non-ASCII header is not properly tagged with a character set and is being used or modified, impose the encoding of the body on the header during processing and final representation of the message? (Many MUAs create non-RFC-compliant headers that are then handled in an undefined way. Some MUAs handle headers encoded in character sets that differ from that of the main body in an incorrect way. Imposing the encoding of the body on the header may encode the header more precisely. This will be used to interpret the content of headers for processing, it will not modify or rewrite the header unless that is done explicitly as part of the processing.) [Y]>
Disclaimers (as either footers or headings) are added in-line with the message body whenever possible.
AsyncOS 12.0 for Cisco Email Security Appliances   - GD( ) 249

  

     

However, if the disclaimer is encoded differently than the message body, and if imposing a single encoding
will cause loss of characters, it will be added as an attachment. The system will always try to use the message body's encoding for the disclaimer. If that fails, the system can try to edit the message body to use an encoding that is compatible with the message body as well as the disclaimer. Should
the system try to re-encode the message body in such a case? [Y]>
If the disclaimer that is added to the footer or header of the message generates an error when decoding the message body, it is added at the top of the message body. This prevents you to rewrite a new message content that must merge with the original message content and the header/footer-stamp. The disclaimer is now added as an additional MIME part that displays only the header disclaimer as an inline content, and the rest of the message
content is split into separate email attachments. Should the system try to ignore such errors when decoding the message body? [N]>

Behavior for untagged non-ASCII headers: Impose encoding of message body Behavior for mismatched footer or heading encoding: Try both body and footer or heading encodings Behavior when decoding errors found: Disclaimer is displayed as inline content and the message body is added as an attachment.
Choose the operation you want to perform: - SETUP - Configure multi-lingual settings. []> setup
If a header is modified, encode the new header in the same encoding as the message body? (Some MUAs incorrectly handle headers encoded in a different encoding than the body. However, encoding a modified header in the same encoding as the message body may cause certain characters in the modified header to be lost.) [Y]>
If a non-ASCII header is not properly tagged with a character set and is being used or modified, impose the encoding of the body on the header during processing and final representation of the message? (Many MUAs create non-RFC-compliant headers that are then handled in an undefined way. Some MUAs handle headers encoded in character sets that differ from that of the main body in an incorrect way. Imposing the encoding of the body on the header may encode the header more precisely. This will be used to interpret the content of headers for processing, it will not modify or rewrite the header unless that is done explicitly as part of the processing.) [Y]>
Disclaimers (as either footers or headings) are added in-line with the message body whenever possible.
However, if the disclaimer is encoded differently than the message body, and if imposing a single encoding
will cause loss of characters, it will be added as an attachment. The system will always try to use the message body's encoding for the disclaimer. If that fails, the system can try to edit the message body to use an encoding that is compatible with the message body as well as the disclaimer. Should
the system try to re-encode the message body in such a case? [Y]>
If the disclaimer that is added to the footer or header of the message generates an error when decoding the message body, it is added at the top of the message body. This prevents you to rewrite a new message content that must merge with the original message content and the header/footer-stamp. The disclaimer is now added as an additional MIME part that displays only the header disclaimer as an inline content, and the rest of the message
content is split into separate email attachments. Should the system try to ignore such errors when decoding the message body? [N]>

Do you want to join or create a cluster? 1. No, configure as standalone. 2. Create a new cluster. 3. Join an existing cluster over SSH. 4. Join an existing cluster over CCS. [1]> 3
While joining a cluster, you will need to validate the SSH host key of the remote machine to which you are joining. To get the public host key fingerprint of the remote host, connect to the cluster and run: logconfig -> hostkeyconfig -> fingerprint.
WARNING: All non-network settings will be lost. System will inherit the values set at the group or cluster mode for the non-network settings. Ensure that the cluster settings are compatible with your network settings (e.g. dnsconfig settings) Do you want to enable the Cluster Communication Service on testmachine.example.com? [N]>
