        msg="This is your daily spam summary:

$nbtotalmsg messages in your Junk folder.
$nbnewmsg new messages in the last 24 hours.
$nboldmsg old messages deleted which were older than 30 days.

You can access your Junk folder through the webmail system:
$webmailurl

You can change your SpamFilter settings through the 'Options' menu
inside the webmail interface, e.g. putting users on the white list
so they won't be marked as spam or blocking users forever through
the black list.

The 'Learn Spam' and 'Learn FP (false positives)' folders are used
to train the spam filter.

When you find a spam message in your regular inbox, you can move it
into the 'Learn Spam' folder so that the filter system can learn from
this message and identify it in future.

When you find a good message in your 'Junk' folder, you can move it
to 'Learn FP' which tells the system that in future it should not
classify those messages as spam. A False Positive is a message that
was identified as spam but shouldn't have.
