Firewall and Proxy Settings
Table of Contents
To display the Firewall Settings window, open the Settings/Connection
window and press the Settings button in the Firewall section:
The program works with SOCKS4/5 or Tunneling proxy servers. Do not confuse
them with the standard HTTP proxy servers that usually work on ports 8080
and 8021. The program is not able to send messages through HTTP proxies.
These types of proxy servers are supported:
- Tunneling Proxy. Default
port number is 80.
- SOCKS4. Default port
number is 1080.
- SOCKS5. Default port
number is 1080.
The User and Password values are used to connect and authenticate to
the given firewall. If the authentication fails, an error is fired during
the sending process.
The Servers section allows you to set addresses and port numbers for
SMTP, HTTP, and DNS protocols separately. If the Address text box is set
to a domain name, a DNS request is initiated and upon successful termination
of the request, the program uses the received IP address to connect to
the firewall. If the search is not successful, an error is returned.
Sets the proxy server address for SMTP connections. The SMTP protocol
is used to send messages.
HTTP requests are used to check for product updates if you enable 'Automatically
check for updates' check box in the Settings/Advanced
window. The program connects to the postcastserver.com server and periodically
downloads a text file which contains information about the latest version
Enter the address of your ISP's DNS server if you have direct connection
to the Internet. If you connect to the Internet through a Local Area Network
(LAN), enter the IP address of the computer on the network that works
as a proxy server.
The TCP port text boxes contain port numbers for SMTP, HTTP, and DNS
services. Note that the port number is set automatically when Firewall
Type is changed.
