F-Secure Server Security for Exchange 9.3
I have a problem with a new white list of file types that need to be active.
Under the transport protection heading, inbound and outbound mail I have created a new white list and populated it with about 25 file extensions preceded with a full stop. So .txt .jpg .pdf and so on. I then save the list.
I then change the drop down menu 'strip these attachments' to all files and then under 'exclude these attachments' to my new white list. Rather than blocking everything except my white list F-Secure simply continues to block everything. I test by sending a jpg file to my personal email account and within 5 seconds I get an F-Secure Postmaster message saying the email was blocked due to disallowed file type.
Is my white list configured correctly? If so how can I troubleshoot this problem?
