Proxy+ is a program that runs on a workstation or a server with MS Windows9x, Windows NT, Windows ME, Windows 2000 or Windows XP and a connection to the Internet. Proxy+ works as firewall proxy server and mail server. All workstations can use Proxy+ services via the TCP/IP protocol.

Connection to the Internet
dedicated (synchronous or asynchronous) or switched line connection
only one IP address, which can be allocated dynamically by the ISP
automatic dialing at user's or mail server's request
automatic hang-up after a defined period of inactivity
week scheduler for an alternate hang-up timeout
support of ISP's modem multiseries
manual dial/hang-up via a WWW interface
Firewall / proxy server
separates the LAN from the Internet to protect from attacks
insecure interfaces (connected to the Internet) are detected automatically
cache increases speed of data retrieval and enables the use of data even if a connection isn't established
proxy cascading enables the use of a parent proxy with or without ICP protocol support
if the ICP protocol is used it is possible to define a few cooperative proxy servers at two levels: parents (at ISP) and siblings (at partnership company)
ICP protocol effectively detects temporarily dead proxy servers and gives users continuous access to requested objects
ability to access a listed source server directly (where access is enabled for permitted IP addresses)


Supported protocols and services:

HTTP proxy for access to WWW pages
HTTPS proxy for access to secured WWW pages
FTP proxy for access to data at FTP servers directly from a WWW browser
FTP gateway for access to FTP servers by FTP clients
Telnet gateway enables terminal access by the Telnet protocol
RealAudio proxy for playing audio/video distributed in RealAudio protocol
SOCKS version 4 and 5 for the access of programs using SOCKS protocols
POP3 mapped link enables easy communication between mail client and mail servers in Internet without using Proxy+ mail server
DNS forwarder translates domain names to IP addresses
configurable DNS cache
Mapped links enable the use of protocols without proxy support (for instance IRC services)


Disc cache

data stored in the cache from WWW and FTP servers increases the speed of retrieval by other users
supports HTTP version 1.1
advanced configuration of cached data validity verification
explicit time-to-live of cached objects
disabling of cache storage configurable


Mail server

sends and receives mail for many Internet mail boxes at one time using the POP3 protocol
full SMTP mail server for one or more domains
option for leaving messages on POP3 server

optional APOP authentication on POP3 server (does not send password in readable form)
messages from an e-mail box can be distributed to user groups
sorting of incoming messages according to configurable rulesets
treatment of MS Outlook and Outlook Express bug prevents from attack by means of Date: message header
users can send messages even if a connection to the Internet isn't established
intranet mail
automatic dialing occurs at defined periods, or if the number of outgoing messages exceeds a defined limit
week dialing scheduler
enhanced support of the ETRN command makes the full SMTP server applicable even on a switched telephone line
restriction of clients' relaying to the SMTP server can be configured to prevent the use of the server for spamming
carbon copy of incoming and outgoing messages to file
mailer masquerade enables the administrator to set the domain name in mail headers
configurable resend if any transfer errors occur
shorter interval between mail exchanges if switched line is connected
configurable timeouts in communication with Internet mail servers
configurable maximum length of outgoing messages
SMTP supports unlimited number of recipients of one message
it is possible to define list of external email addresses
it is possible to schedule sending of a message at special time interval (large messages, low priority messages)
it is possible to view messages ready to send (outgoing queue) and it is possible to delete a waiting message using WWW Admin interface
plugin support which allows to check messages for viruses and dangerous attachments
possibility to forward messages downloaded from POP3 servers or received by SMTP server to another local or remote recipients
