Switches the attachment filter on or off.
The sender will receive a warning from Kerio MailServer, that he/she has sent a message with a virus or blocked attachment.
The message will be forwarded (intact — with possibly infected or forbidden attachment) to the email address specified. It is not important whether the address is local or remote.
The message without an infected or prohibited attachment will be (apart from the actions selected below) forwarded to the specified email address as well. This can be used for verification of proper functionality of the antivirus and/or attachment filter.
Displays individual filters. To the left of each filter there is a checkbox that you can use to enable or disable the filter. Use these checkboxes to switch filters off without the need to remove them.
After the Kerio MailServer installation, there is a list of several predefined filters. All filters are turned off and the administrator can choose to enable or remove them. This way for example executables (
.exe), Visual Basic scripts (
.vbs), etc. can be filtered.
Use thebutton to add a new filter:
Text description of defined filter.
Defines if attachments will be filtered based on file names or MIME type (Multi-purpose Internet Mail Extension).
Enter either the file name (you can use the asterisk convention for e.g. filtering files with a certain extension — e.g.
*.exe) or the MIME type name (for example
application/*). You can also choose one of the pre-set or MIME types.
An action will be performed as defined above the list of disabled attachments (described above).
Attachments will not be removed from messages and no other rules will be applied.
