This SMTP/POP3 server is robust and secure with anti-spam and security features. It has multiple SMTP gateways and enables sophisticated macro substitution for mass mailing. The server is easy to set up and intuitive to use.

E-Mail Server allows you to accept, forward, store, and deliver mail on behalf of your users in a corporate environment, or even as an individual. Your users can receive their messages using POP3, and you have incredibly fine granular control over who can send messages, who can receive them, and how big their mailbox size may be.
Take your entire domain down for maintenance with just one click of a button or manage your large mailing lists with ease. Regardless of how big or small your list of users may be, you can distribute separate and personalized messages to each one of them effortlessly.
E-Mail Server is the ultimate solution when it comes to controlling multiple parameters of your server to prevent any malicious attacks or unauthorized use. You can filter out spammers even before they start sending you a message, thanks to the real-time blocking (RBL or DNSBL) feature that filters out most spammers at the source.
In short, E-Mail Server is an excellent choice for anyone looking for a reliable and user-friendly email server program.
