Folder names can be entered by prefixing them with a hash ('#') sign. This will cause a copy of the message to be saved in the folder with this name. If no such folder exists, it will be created in the mail folder directory. For example, entering ``joe.user@foo.com, #myMail'' in the To: field, will send the mail to Joe User and save a copy of it in the folder ``myMail''. Note, that if you have your folders organised hierarchically, you must specify the full path to the folder in the folder tree control. An example: If you have a group of folders in the tree, called ``Work'' and want to save a copy of the message to the folder ``TODO'' which is a sub-folder of ``Work'', you need to add ``#Work/TODO'' in the address field. Instead of using the To: field for this, you can also use CC: or BCC:, there is no difference.
