Note: Kerio MailServer’s spam filter can be set so that the Subject entry will include
results of antispam tests (the value is represented by asterisks). Using this feature
spam may be filtered easily. Simply insert the number of asterisks that will specify
the rule. Messages that match this rule will accept this specification.
Where the message has an attachment
At least one attachment must be appended to the message.
Usage example: It is useful when combined with the Where the message size is
more/less than size rule if a quota is applied to the mailbox and all messages larger
than the set limit should be sent to another mailbox where you have enough space.
Where the message size is more/less than size
The message size exceeds the specified value. To specify the size you can select from
the following units: bytes (B), kilobytes (KB) and megabytes (MB).
Usage example: It is useful if a quota is applied to the mailbox and larger messages
should be sent to another mailbox where you have enough space.
Where the message was detected as a spam
Spam are undesirable messages sent to users. You can use the Kerio MailServer anti-
spam filter to protect your users from such messages. This filter uses special header
items which include message evaluation and information about applied antispam
testing.
For all messages
