WASP Mail Server is a complete email messaging solution designed for small to mid-sized businesses and is backed by the industry’s best technical support team.

Works With All Devices

WASP Mail Server is a complete email server with SMTP, POP, IMAP, LDAP, and List Server. WASP users can send and receive email using any standards-based client, including Microsoft Outlook®, Outlook Express®, or Eudora®.

Built-In Features

Standards-compliant support for LMTP, STARTTLS encryption, SASL authentication, MIME encapsulation and transformation, DSN delivery status notifications, IPv4, and IPv6

Modular Design

The modular architecture of WASP forms the basis for its security. Each WASP process runs with the least amount of privilege necessary to get its particular job done.

Shells and Processes

In most cases, delivery of mail does not require a Unix shell process, but when a configuration does make use of one, WASP sanitizes information before placing it into environment variables.


WASP architecture limits the severity of vulnerabilities, even if there are designs or coding errors that might otherwise create major vulnerabilities in a monolithic privileged program.
