Select Data to Log

Log all local MDSpamD activity (debug logging—performance drain)

Use this option to log all local MDSpamD activities (see Caution below).

Log sessions in real time (debug logging—performance drain)

Ordinarily, session information is logged after the session is completed in order to conserve resources. Click this option if you want session information to be logged as it occurs.

| When using either or both of the previous two logging options, you may see decreased performance in your mail system, depending on your system and the level of activity. Generally you should only use these options for debugging purposes.

Log multi-line protocol responses (like UIDL and LIST)

Sometimes the responses to protocol requests require more than one line of information. Click this checkbox if you want to log these additional lines.

| Enabling this switch could potentially increase the amount of logged information a great deal. Because the number of lines in a response can't be determined in advance, and because some responses have great potential for "filling up" your log file with possibly unnecessary information (POP TOP, for example, lists the actual contents of the message), we do not recommend using this feature if log file size or verbosity is of concern to you.

Log ID string in mail session logs

Click this check box if you wish to include [%d:%d] ID strings in session logs.

Use colors when displaying mail session logs (requires MDaemon restart)

Enable this option if you wish to colorize the text displayed on several of the Event Tracking and Logging tabs on MDaemon's user interface. This option is disabled by default, and enabling/disabling it requires an MDaemon restart before the change will take effect. See: "Colorized Session Logs" below for more information.

Always log to screen

Click this option if you want the logged data to be copied to the MDaemon GUI even when it is minimized or running in the tray.

When this control is cleared, log data isn't copied to the Event Tracking pane when MDaemon is running in the system tray. Consequently, the most recent activity won't be listed on any of the Event Tracking pane's tabs when MDaemon is first opened. It will begin displaying newly logged information from that point forward.

### Colorized Session Logs

On MDaemon's user interface, the tabs that display Routing, SMTP-in, SMTP-out, IMAP, POP, MultiPOP, and DomainPOP activity can be colorized to help visually separate events during a session. This features is disabled by default, but can be enabled via the "Use colors when displaying mail session logs" option located at: Logging » More Settings and Preferences » UI. The default text colors can be changed by editing the [Colors] section of the LogColors.dat file in MDaemon's \APP\ folder. See the chart below for a list of the default colors.

If you want to use colors but don't want to colorize one or more of the listed elements, set value of each of those elements to zero (for example, SpamFilter=0). This will cause the chosen elements to use the Default color. For Background and SelectedBackground, however, setting their values to zero doesn't work. If you want to change either of those elements you will have to provide a new color value. Color values are specified in hexadecimal using this form: "0xbbggrr", where "bb" is the relative intensity for blue, "gg" for green, and "rr" for red. For example, "Error=0x0000ff" sets error text to red. Please note: this is the reverse of the traditional order for color codes, which is typically "rrggbb". If you make changes to the colors, you must restart MDaemon or create a file called COLORS.SEM and place it in MDaemon's \APP\ folder.
