Viaaliasrequired, viaaliasoptional Channel Options

Require use of aliases
The default is, meaning that an  alias match and resulting expansion are not required to be part of address processing prior to enqueing to this channel. If  is specified on a channel, then only addresses whose processing involved expansion of some sort of alias (LDAP entry,  alias file entry,  alias database entry, etc.) are allowed to be enqueued to the channel.

Note that  must be used on the local  channel for direct LDAP configuration  to work properly.
