  • <host>:<port> (by default 127.0.0.1:10025) (SMTP) for operation of the mail transfer agent (MTA) filter, if MTA Filter is configured to accept connections, for example, from an external MTA over the TCP (SMTP) protocol.
  • <host>:<port> (by default 127.0.0.1:10025) (Milter) for operation of the mail transfer agent (MTA) filter, if MTA Filter is configured to accept connections, for example, from an external MTA over the Milter protocol.
  • <host>:<port> (by default 127.0.0.1:2711) (FCGI/TLS) for the Facade module to access the program web interface.

  • <host>:<port> (DNS) for operation of Mail Sender Authentication technologies (DNSBL, SURBL, SPF) and the Anti-Spam module.
  • <host>:<port> (SMTP) for operation of the mail transfer agent (MTA) filter if MTA Filter is configured to send email messages to an external mail server over the TCP protocol.
  • <host>:<port> (HTTPS) to connect to the program database update server.
  • <host>:<port> (HTTPS) for the connection between the Moebius module (for instantaneous updates of Anti-Spam databases) and the enforced database update service.
