AXIGEN Mail Server can use different Listeners for its TCP services (SMTP Receiving, POP3, IMAP, WebMail, WebAdmin, CLI, FTP Backup& Restore, POP3 Proxy, IMAP Proxy and Webmail Proxy) and UDP services (Log and Reporting).

Listeners are network points of entry associated with an interface address and port number that grant access to a specific TCP or UDP service.

Listeners add extra flexibility and configurability to each AXIGEN service as they can be used to grant differentiated access to the same services for different categories of users (e.g users within a specific domain). Moreover, listeners can be associated with a variety of rules that allow defining specific limitations for connections coming from IPs within specified IP sets.

Listeners can be defined, using various parameters corresponding to that TCP service, from the configuration file (as of type "TcpListener" OBJECT-SET) or through WebAdmin (the web configuration interface). UDP service listeners have fewer parameters associated as connection related parameters do not apply to them.
