command line mail - set parameter from text file
-USEFILE or -UF is an universal parameter that allows to specify a text file that contains command parameters instead of typing parameters into command line. This command greatly facilitates using command line mail utility (e.g. using -USEFILE with -TO switch instead of providing large list of comma separated email addresses, or also, using -USEFILE with -TEXT switch that allows to send pre-formatted or automatically generated text files preserving line feeds, tabs etc.).

-USEFILE switch can be used after any command that requires specifying value (variable). In this case, value of variable is taken from the specified file not from command line.
C:\>febootimail -SERVER -UF server.txt -FROM -UF from.txt -TO -UF recipients.txt -SUBJ -USEFILE subj.txt -TEXT -USEFILE message.txt -COMMENT substitute every parameter with text file when using DOS command line mail by using USEFILE or UF paramWhen using batch files, -USEFILE becomes even more powerful feature that allows to use both dynamic and static text files to specify command line mail sending process.
