E-mail domains (ISPmanager)

From ISPWiki

Jump to: navigation, search

An e-mail domain is a collection of Mailboxes, Mail groups and e-mail redirects that are associated with one domain name. All the e-mail boxes, groups and redirects associated with one e-mail domain have the same part after the "@" sign in the e-mail address.

The e-mail server will process domain's email, if the domain name is specified in the file /etc/mail/local-host-names.

This module can be used to create new e-mail domains, edit and delete existing ones, view e-mail boxes, redirects and e-mail groups of a specific mail domain.
