MarTPost is a SMTP (Simple Mail Transfer Protocol) Server. It enables you to send mail directly from your computer, without needing an external mail server. It is designed for those who don't have access to a SMTP server for sending mail. Although SMarTPost doesn't collect mail, it allows those without ISP SMTP access the ability to prepare emails offline, and then go online to send mail through SMTP, rather than slower, Webmail services. SMarTPost may be used over an intranet connection, or may allow other users access to its features from other computers on the Internet. Version 2.5.3 may include unspecified updates, enhancements, or bug fixes.
