                          PostLink(tm) Software

Summary:

PostLink is a new BBS networking program from the creators of PCRelay.
It is a complete rewrite, merges the PCRelay HUB and NODE software into
one integrated program.

It contains many new or enhanced features, including greatly enhanced
file requests, the ability to route messages to more than one site
("multicasting") or to all sites on your network ("broadcasting"), much
greater flexibility in configuration, integrated communications
including built-in communications protocols, full support for multiple
compression programs and external communications protocols, including
bi-directional protocols such as HS/Link, and greater support for LANS
and multitasking BBSs.  Postlink allows for alternate delivery of public
mail packets, allowing you to obtain your mail via less expensive or
faster means than phone calls to a hub.

PostLink continues to support the UTI specification, and has been
designed to be able to support more BBS's internally, although at this
time the only BBS that is supported internally is PCBoard.

More Detailed Information:

PostLink is the next generation of networking software for BBS's.  It
picks up where PCRelay leaves off, greatly enhancing many of the
features that have made PCRelay one of the most popular networking
options for Sysops everywhere.

PostLink was written from scratch in standard C++.  It has been designed
with large capacities and great portability in mind.  However, thanks to
its extremely flexible configuration system, it can efficiently run
small networks just as well, while providing room to grow.

PostLink was designed to be able to handle networks of 10,000 sites or
more. PostLink 1.0 will support around 16,000 conferences, and is
designed to be able to support up to 4,294,967,296 conferences, which
should be able to support networks well into the future.

PostLink has been specifically designed to be able to perform well on
multi-node BBS's. PostLink locks resources for writing on a conference
by conference basis, and allows simultaneous reading of conference files
for maximum efficiency in a multitasking or LAN environment.  PostLink
is even smart enough to go work on another conference and come back to
the original conference if a particular conference's files are busy at
the moment!  This means that less online time is spent waiting for
someone who is on another "node" of the BBS to finish getting their
mail, and it makes it feasible to have much larger hub systems.

PostLink integrates the NODE and HUB versions into one package.  This
means that mail can be imported directly onto the BBS when mail is
uploaded into the hub. Separate EXPORT and IMPORT programs are also
provided in case it is desirable to control when mail is exported and
imported.

In addition to integrating the NODE and HUB portions of the software,
PostLink adds a built-in communications module which can learn how to
log onto your hub.  Thus, it is no longer necessary to use a "script"
file with another communications program; you can now simply "teach" (by
logging on and entering the PostLink door) PostLink how to get to the
door on the board you call, and from then on PostLink can handle all the
communications itself!  PostLink also retains the flexibility of being
able to use an external communications program, allowing even unusual
communications situations to work.  (i.e. diskette copying, etc)

PostLink adds _extensive_ error detection and logging, including leaving
the Sysop of the BBS messages when there are non-fatal errors.  In
addition, if a user enters a message that is not exported or that is
misrouted, PostLink sends back a detailed message explaining what
happened, and often suggesting what to do about it.

PostLink now allows both the compression and communication protocol
options to be configured by the SysOp, allowing new protocols and
compression programs to be implemented as soon as they are released.
PostLink fully supports bidirectional protocols such as HS/Link.  In
addition, PostLink has a number of built-in protocols, including ZModem.
PostLink can be configured to use just about any compression program,
including none.  Using no compression can be desirable in situations
where the modems being use have good compression already.

PostLink utilizes the UTI 2.x specification to get mail onto and off of
BBS's, so any BBS that has a UTI 2.x driver (such as RBBS, Wildcat!,
GAP, Spitfire, MajorBBS etc) can use PostLink.  In addition, PostLink
has built-in support for PCBoard 14.5 and 15.0, including updating mail
waiting flags and the call waiting screen statistics, if desired.
PostLink has been designed to make it as easy as possible to add
built-in support for other BBS programs, so you should definitely expect
built-in support for other BBSs in the future!

PostLink attaches "audit records" to every message and file as it passes
through the network, allowing for detailed debugging and performance
information.  Now you can find out why a message took 3 days to get
somewhere -- the audit information will show you all of the systems that
the message went through, and what time it arrived on each of those
systems!  These audit records are utilized in the Return Receipt mail
option to show you not only that your message has arrived at its
destination, but how it got there and why it got to the destination
system when it did.

PostLink provides advanced mail functions such as automatic encryption
of all routed mail, full reference number support, multicast routing,
and automatic routing. Multicast routing is the ability to route a
message to several different systems. The message will only show up on
the systems you specify. Automatic Routing is a unique PostLink feature.
Automatic routing will automatically route private replies back to the
BBS where the message the reply refers to was written.  This means that
it is no longer to setup and maintain a private mailbox system.
Automatic routing is both efficient and secure.  It is more efficient
because the message is routed once by the site sending it and it more
secure because Sysops can not add users to their PRIVATE.NET files in
order to "snoop" on their private mail.  Since the messages are routed
and encrypted, only the origin and destination sites can see the
message.

It's not only the message facilities that have been improved in
PostLink, however.  The file request system has been greatly enhanced,
now allowing as many directories to be requestable as you like, with
ability to associate passwords and/or site numbers with file directories
or even individual files to control not just what files can be requested
from your system, but who can request them.
