Alias entry alias option

Alias options:  (alias or address)
The  alias option is the fundamental part of an alias: it specifies a translation address (or alias) for an alias. For an alias that translates to multiple addresses or aliases, multiple   settings may be made. Each value specified as an  may be a fully qualified address, or a short form alias name itself. Each individual  value corresponds to what in legacy configuration would be one address or alias on the right hand side of an alias. The entire set of  values for an alias corresponds to what in legacy configuration would be the list of addresses/aliases on the right hand side of an alias.

Every MTA configuration should include at least a postmaster alias. E.g., msconfig&#x3e; show alias.&#x2a; role.alias:root@default-domain.alias_entry = postmast role.alias:root@mta-host.alias_entry = postmast role.alias:postmaster@mta-host.alias_entry = postmast Since the initial configuration creates in LDAP a postmaster group with    as the primary address (  attribute) and with    as an alias  (  attribute), these alias entries ensure that alternate "postmaster-ish" sorts of addresses, such  as for instance   , will be directed to the postmaster group.

The distinction between   and   is the distinction between the default domain for users&#x27; e-mail addresses, vs. the (possibly different -- indeed a different name is recommended) DNS name of the host system itself. For instance: msconfig&#x3e; show alias.&#x2a; role.alias:root@example\.com.alias_entry = postmast role.alias:root@host\.example\.com.alias_entry = postmast role.alias:postmaster@host\.example\.com.alias_entry = postmast
