Reply-To field in email header specifies an address to which possible answers will be sent. If -REPLYTO switch is not used, From address is used as Reply-To address. However, some specific situations may require Reply-To address to differ from FROM address.
febootimail -REPLYTO firstname.lastname@example.org
For example, some marketing department is sending out news to their listed customers, but all further questions and replies are served by customer support department. In such situations or alike it is reasonable to use marketing department email as FROM address and support department email as REPLYTO address.
C:\>febootimail -SERVER smtp.server.com -FROM email@example.com -TO firstname.lastname@example.org -REPLYTO email@example.com -TEXT a DOS mail sent using Reply To parameter
Also, note that more than one address can be specified in Reply-To field. In this case, depending on email client software behavior, reply will be sent to all mails contained in Reply-To field.
Please do not hesitate to contact our support department with any possible further questions or to solve practical issues connected with Command line email.
