The mail client can be used to send mail to arbitrary mail addresses, though when the panel appears, it is pre-loaded with the address of Whiteley Research technical support. The text field containing the address, as well as the subject, can be changed.
The main text window is a text editor with operations similar to the text editor used elsewhere in Xic and WRspice. The File menu contains commands to read another text file into the editor at the location of the cursor (Read), save the text to a file (Save As) and send the text to a printer (Print). When done, the Send Mail command in the File menu is invoked to actually send the message. Alternatively, one can quit the mail client without sending mail by pressing Quit.
The Edit menu contains commands to cut, copy, and paste text.
The Options menu contains a Search command to find a text string in the text. The Attach command is used to add a mime attachment to the message. Pressing this button will cause prompting for the name of a file to attach. While the prompt pop-up is visible, dragging a file into the mail client will load that file name into the pop-up. This is also true of the Read command. Attachments are shown as icons arrayed along the tool bar of the mail client. Pressing the mouse button over an attachment icon will allow the attachment to be removed.
In the Windows version, since Windows does not provide a reliable interface for internet mail, the mail client and crash-dump report may not work. Mail is sent by passing the message to a Windows interface called ``MAPI'', which in turn relies on another installed program to actually send the mail. In the past, the mail system was known to work if Outlook Express was installed and configured as the "Simple MAPI mail client". It is unknown whether this is still an option with recent Windows releases.
To get mail working in Windows 8, it was necessary to download and install something called ``live mail'' from Microsoft, which eventually worked. This application supports MAPI, apparently the default Windows 8 Mail application does not. The default Windows 8 Mail application also does not work with POP3 servers.
