FineLine Internet MailServer

Easily send & receive Internet email with UNIX


FineLine Internet MailServer enables a UNIX system to start sending and receiving Internet email using standard SMTP and POP3 in literally minutes, eliminating the need to set-up and maintain complicated sendmail or mmdf and provides the ability to send email with attachments directly from your UNIX application.

It also includes both SMTP and POP3 servers for connecting PCs and other systems to Internet email through the UNIX Internet connection.

It provides a powerful, flexible, easier-to-use and much less expensive alternative to PC-based mail server products like Microsoft Exchange.


The key to FineLine Internet MailServer's ease in set-up and use is that it makes the multiuser UNIX system look like a regular PC email program (ex: Outlook, Thunderbird, etc) to your Internet Service Provider (ISP) so it can use a standard Internet PC account yet still support multiple users receiving email in the same mailbox.

  • Enables having an entire company send and retrieve Internet email with a single Internet account

  • Addition and deletion of users is all done locally, without requiring any contact with the ISP or changing any mailbox names

  • Provides the functionality of the system mail program without the setup and maintenance headaches

  • Includes SMTP & POP3 servers for connecting PCs and other systems to the FineLine Internet MailServer, enabling them to access Internet email through the UNIX Internet connection

  • Works transparently with the FineLine Message Manager, or any UNIX email interface program

  • Includes a basic email filtering system for weeding out unwanted email messages

  • Includes a POP mailbox maintenance program that enables accessing a mailbox on the Internet interactively. This feature enables viewing and printing message headers or entire messages, and deleting any combination of messages without having to download them to your system (a great way to delete a troublesome incoming message before it gets to your system).

  • Enables attaching multiple files to a message with standard BASE64 from a command-line

  • Includes an "auto-attendant" feature that can automatically detach and process data files attached to incoming messages

  • Supports multiple domain names on the same system and multiple Internet POP email accounts

  • Handles incoming & outgoing system mail functions including returning mail with an announcement, auto forwarding, return-receipt, user name mapping and more

  • Supports Authenticated SMTP servers (starting with version 2.1 - see below for upgrade information)

  • Takes only minutes to install and configure


To send email from UNIX, FineLine Internet MailServer requires access to a standard authenticated SMTP server.  This is usually available from the Internet Service Provider that is providing the Internet access.  Note that the SMTP server must not require encryption (SSL/TLS) so services like gmail and yahoo will not work.

For incoming mail support, either a registered Domain Name with Virtual Domain Support from the ISP (so all incoming messages for a domain name are placed into one POP3 mailbox) or the ISP forwards each incoming message directly to the MailServer's SMTP server for local delivery (requires your UNIX server to be running 24/7)

Supported UNIX platforms

  • SCO OpenServer 5 / 6
  • SCO UnixWare 7
  • Linux
