ArGoSoft Mail Server .NET is continues best traditions of their
older, Win32 based mail servers. It uses concepts and methods,
used, tested and approved by tens of thousands of users since they
first released their first mail server in 1999.

But, the .NET version uses more advanced database engine, and
contanins 100 managed code (.NET), which make it more reliable,
efficient, fast. The difference in speed is more noticeable with
IMAP and the Web interface.

It contains two modules:
Mail Server module itself, which is a Windows service
application, and provides SMTP (including secondary SMTP), POP3,
IMAP and delivery services. It also supports Mailbag domains
and has built-in anti-spam and security features.
An optional web interface, which is a ASP.NET application, and
allows an access to email (access to server administration will
be added later). It is free, and comes with source code,
allowing easy customization and localization.
