Settings for Messages Containing Multiple Encodings
You can define the behavior of the appliance while modifying the message encoding for the following 
parameters:
Headers
Untagged non-ASCII headers
Mismatched footer or heading encoding
To configure this behavior, use the localeconfig command in CLI. 
Note
This behavior cannot be configured using web interface.

Total Time Limit for All 
Inbound Connections
Set the length of time AsyncOS will allow an inbound connection to remain 
intact before closing it.
This setting is intended to preserve system resources by enforcing a 
maximum allowable connection time. Once about 80% of this maximum 
connection time is reached the following message is issued:
“421 Exceeded allowable connection time, disconnecting.”
The appliance will attempt to disconnect when the connection exceeds 80% 
of the maximum connection time in order to prevent disconnecting 
mid-message. It is likely that a problem is occurring with the inbound 
connection if it is open long enough to reach 80% of the maximum 
connection time. Keep this threshold in mind when specifying the time limit.
Only available for SMTP connections on public listeners. The default value 
is 15 minutes.
Maximum size of subject
Messages having subject size within the specified limit will be accepted and 
any other messages will be rejected. If you set this value to 0, no limit is 
applied.
