How can I add remote internet recipient to my Scalix directory?
From Scalix Wiki
A remote internet recipient is typically an address that people want to see in the SYSTEM directory that ultimately routes to a recipient outside of Scalix. It can be added using the omaddent command.
For example:
# omaddent -e CN="First Last"/OU1=internet/IA=first.last@domain.com
or
# omaddent -e CN="Last, First"/OU1=internet/IA=first.last@domain.com
The most important part is to set OU1=internet, which is a automatic route that is setup when Scalix is first installed.
