Encaps2SMS checks your mailboxes, when you leaves the computer, and sends notifications about new E-mails onto your cell phone by SMS. You can configure leave timeout, mailbox access settings (ssl, auth, unlimited mailboxes support), SMS sending parameters (SMTP-server, ssl, auth), spam filtering (white-list and black-list sender & subject check). User interface is intuitive and simple. Version 0.9.1 may include unspecified updates, enhancements, or bug fixes.
