Unknown Recipients
If a message arrives that is addressed to a mailbox that does not exist within your domain then the Unknown Recipients page lets you specify what happens to that message. For example,
if you have set up WorkgroupMail with the domain mydomain.com and you have defined mailboxes john, sue and mike, then WorkgroupMail will know how to deliver
messages sent to john@mydomain.com, sue@domain.com and mike@domain.com . However, if a message arrives addressed to paul@domain.com, WorkgroupMail needs to know
which user to forward this message to.
You can specify the user to whom WorkgroupMail will forward all messages sent to unknown recipients by selecting the appropriate user from the drop down list in the Unknown Recipients page. Press
OK to save your changes.
