How to use the “Export All Existing Mails to External Mail Server”?
If back-end email server does not respond for a period of time, Europa can manually or automatically switch from SPAM filter mode to email server mode. All the queued or incoming email are then stored into Europa. The user can use Web email client to access to those new emails. After the back-end email server is up, you can export either ALL or From Last Export emails back to the email server.
