The server automatically creates an email alias for each group. If you want to define an email alias for a list of users, simply create a group and the list is automatically maintained by the server.
Pseudonyms allow you to create other names for existing users or groups. For example, you may wish to create a pseudonym "webmaster" for your "webdevelopers" group or a pseudonym "joe" for the user "joseph".
The server automatically creates pseudonyms in the format of firstname.lastname and firstname_lastname for every user on the system as well as a pseudonym "everyone" which contains all users on the system.
To create an email pseudonym for an account or group:
Under Collaboration, click create Pseudonyms.
Click Add pseudonym.
Enter the pseudonym. A pseudonym can only consist of the following:
lower-case letters,
numbers
periods
hyphens,
and under scores
For example, "sales", "john.hollan", "123", and "email-administrator" are valid pseudonyms, but "John Smith" or "Henry Miller" are not.
Select the account or group to which you want the pseudonym to apply.
Click Add.
To modify or remove a pseudonym click the Modify or Remove command next to the pseudonym.
