. 

When making an LDAP routing query, if the user portion of the original email address 
is same as that of the user portion of the routed address, the query fails.

TLS verification against some of the hosted cloud email services fails, where cloud 
provider presents a common certificate for all hosted domains.

Some messages are not encrypted as expected. 

This can occur if "TLS Required - Verify Hosted Domains" is enabled for the 
Destination Domain and the destination Mail Transfer Agent (MTA) does not offer 
STARTTLS. 

Workaround: Do not enable "TLS Required - Verify Hosted Domains." 

Emails are sent to incorrect mailhosts after LDAP routing. This issue occurs when the 
configured LDAP contains multiple LDAP entries with the same mailLocalAddress 
field.

Workaround: Not available

Upgrade to latest AsyncOS which is having Expired Sophos Engine will alert the user 
stating that it is expired. This issue occurs when user upgrades to latest available 
AsyncOS which has Expired Sophos Engine. An alert will be sent to user stating that 
the Sophos engine is expired. 

Workaround: You can ignore this alert. After the upgrade, auto-update will 
download and update the Sophos Engine to the latest available version.
