By default, the POP server will give you a view onto your Inbox and nothing else. However, the Zimbra POP3 server
will let you specify a different default POP query. Please check out the "POP3 Easter Egg" section of
this old blog posting for details.
In short, configure your client to log in as
user1{folder:bugs tag:p1} if you want POP to return all messages in the "
bugs" folder and having the "
p1" tag. Replace "
user1" with your login name and "
folder:bugs tag:p1" with your query as appopriate.
