Stalwart SMTP server is enabled by creating one or more listeners. A listener essentially acts as a point of entry for SMTP or LMTP connections, listening on a specific port for any incoming connections. Administrators can set up multiple listeners, each potentially serving different roles or catering to different types of connections. Stalwart SMTP imposes no limit on the number of listeners that can be created, providing administrators with the flexibility to manage incoming connections as they see fit.
