UserGate mail proxy
UserGate mail proxies are designed to support both the POP3 and SMTP protocols, as well as to scan mail traffic for viruses. By using either a POP3 or SMTP proxy in transparent mode, the mail client setup on the user workstation is the same as a direct Internet access setup (no proxy).
If UserGate POP3 proxy is used in non-transparent mode, you do need to specify the UserGate workstation IP address and port that correspond to the POP3 proxy as the POP3 address in the client settings of the user workstation. In addition, you need to specify the login for the remote POP3 server authorization in the following format: e-mail_address@POP3_server_address. For example, if the user e-mail is firstname.lastname@example.org, you should enter email@example.com@pop.mail.ru as the login for the UserGate POP3 proxy. This format is necessary for UserGate to detect the remote POP server address.
If UserGate SMTP proxy is used in a non-transparent mode, you need to specify the SMTP server IP address and port in the proxy settings section. In this case you enter the UserGate Server IP address and port that correspond to the SMTP proxy as the SMTP server address in the mail client settings of the user workstation.
If authorization is needed for sending mail, please enter the username and password that correspond to the SMTP server shown in the UserGate SMTP proxy settings.
