In the late 90's, I began selling several command-line programs for Windows using the shareware model. I sold a command-line SMTP mailer (MailSend), a command-line POP3 reader (MailGrab), a command-line scheduler (TSched), and a command-line Dial-up-networking disconnect utility (HangUp). Total income over several years was in the low five-figures when bundling deals were included ( some people wanted to include these programs as part of bigger systems that they sold ). I created a successor to MailSend called MailWrench that provided better support for Microsoft Exchange Server and SMTPS (SMTP over SSL), but the market just didn't seem to be there for command-line mailers any longer. These programs are now free-to-run software with source ( with the exception of MailGrab).
