Through Service Configuration system administrators can manage logging, HTTP protocol, WebMail session and thread management parameters.
Logging
You can select several types of messages to be logged for the WebMail service: critical messages, error messages, warning messages, informational messages and protocol communication. To select which of these are to be logged, click the Log Level slider and move it to the left or to the right. The selected types of messages will change color from whiter to gray.
Log files can be stored using your internal log files, your system's log files or within the log files located on a remote system. Use the Log drop-down menu to select where to have your log files saved.
HTTP Protocol Options
Next, you can set the HTTP limits for WebMail requests. Use the Limit HTTP Request header to option in order to specify the maximum allowed size for incoming HTTP headers, and the Limit HTTP Request body to option in order to specify the maximum allowed size for incoming HTTP body. The third option, Limit file uploads, can be used to set the maximum allowed size for incoming upload data. It applies to attachments, mail body and contact import operations. All size values can be set by using the up and down arrows, in KB or MB.
Select the appropriate action to be taken when the incoming data is over the set limits by using the If any of the above limits is exceeded option. Use the drop-down menu in order to choose between closing the connection immediately or allowing all data to be sent.
Webmail Options
Use the Allow domain selection on login option in order to display or not the domain list when logging in to WebMail. Enable it by just checking the box in front of the option. If you wish to allow mailbox access from mobile devices check the Enable Mobile User Interface option.
Set the parameters for WebMail sessions by using the two options under Session. You can specify after how many seconds an inactive (idle) WebMail session is closed, and specify after how many seconds a WebMail session is closed, even if activity exists. Values for these parameters can be entered only in seconds, by using the up and down arrows.
Thread Management
Thread management allows you to set different numbers of processing threads for the SMTP Receiving service, depending on your traffic load. First, using the up and down arrows, set a number of threads to be allotted when the SMTP Receiving service is started. To have a different number of threads for peak periods, check the overload option and use the up and down arrows to choose the thread number.
When you are done configuring these parameters, remember to hit the Save Configuration button to preserve your changes.
