5star Mail Server is an extremely-reliable and fast SMTP/POP3 server. It can be used as a replacement of your corporate email server, since once configured it allows the email to be sent and retrieved using any email client software that supports SMTP and POP3 protocols. The server has a built-in support for mailing/distribution lists allowing you to configure groups of email receipients that may all receive an email message sent only once. The 5star Mail Server provides enhanced security and anti-spam features.
