Neat little program...
"Minimail is a small, convenient and easy to use tool for the creation and sending of plain text e-mails. Minimail features file attachments, multiple accounts, signatures, logging, SMTP authentication, undo and redo, view settings and more. Its primary purpose is to provide a quick and easy way to send e-mails without the need to open your bulky, full-featured e-mail client. Minimail is fully resizable and can be minimized to the task bar or the system tray. It can also be set to the default mail client to load automatically when a "mailto:" link is clicked in your web browser."
