Michael,

It looks like we're still working the kinks out of the new web site. Should
be OK soon. Please send email to info at fsl.com if you have any questions or

Thanks,

> > BarricadeMX is a new lightweight, small footprint computer-based
> > anti-spam application. It is
> > designed as an SMTP port 25 proxy, filtering and forwarding mail to
> one
> > or more local or remote mail transfer agents. BarricadeMX supports a
> > variety of well blended anti-spam filtering tests that can be
> > individually enabled or disabled according to the rigors of the
> > postmaster's local filtering policy. Most of these tests are optional
> > and several are configurable by Domain. BarricadeMX can also set
> limits
> > on message size by sender, recipient, domain, IP address and IP
> address
> > ranges.
> >
> > The application itself is a small (4 MB resident memory),
> lightweight,
> > multi-threaded C program. Much more efficient than the typical MTA,
> it
> > can gracefully handle many simultaneous incoming connections. A
> single
> > CPU system has handled 1018 concurrent SMTP client connections
> without
> > failing or losing any legitimate mail. Many servers that are in
> > production routinely handle 200 to 300 incoming simultaneous
> connections
> > while maintaining low CPU utilization.

> > BarricadeMX may be configured to run on multiple gateways which share
> > multicast or unicast caches. These caches provide a fast, simple, and
> > efficient means to share cache updates across multiple gateways on
> the
> > same network segment or back and forth to a set of remote hosts. Both
> > the multicast and unicast caches use a broadcast-and-correct model
> and
> > support IPv4 and IPv6.

> > By rejecting messages with a 550 error at the MTA level during the
