-REPLYTONAME parameter allows specifying friendly name of reply recipient instead of just address e.g. John Doe versus email@example.com. In that way, replying user knows to whom she replies, since the recipient of reply is not necessarily the person who sent the original message.
febootimail -REPLYTONAME John Doe
Note, that using -REPLYTONAME requires using -REPLYTO parameter as well.
C:\>febootimail -SERVER smtp.example.com -FROM firstname.lastname@example.org -REPLYTO email@example.com -REPLYTONAME Support Department -TO firstname.lastname@example.org -MESSAGE "Send email from CMD with reply name specified"
Alternatively, it is possible to specify friendly address using -REPLYTO parameter:
-REPLYTO "John Doe <email@example.com>"
