@sergey.popov2: I think you mean callback verification. ORF does not have such feature, because the concept itself has many problems (for one, your server could flood innocent victims of forgery with callbacks):

@yevgeniy: Please send us the following to :

• A short description of your setup (operating system, Exchange version, are there any other filtering software affecting emails, secondary MXs, perimeter servers in between the senders and your server, etc.)
• Your current configuration file called orfent.ini (located in Program Files (x86)\ORF Fusion by default)
• Your .log files from the past few days (e.g., orfee-2014-06-12.log, orfee-2014-06-11.log, orfee-2014-06-10.log etc. located in Program Files (x86)\ORF Fusion by default). Please send raw .log files, Log Viewer CSV exports are not suitable.
• A few spam samples with bogus sender addresses, which made it through filtering, which consist of the original emails in EML or MSG format (EML preferred) and the original MIME header in a separate TXT file. (Forwarded emails are not suitable). The MIME header can be retrieved by opening the email in Outlook and selecting View | Options... (or Message options) from the menu. If you use another email client and do not know how to retrieve the email headers, please visit for instructions.

I will review your configuration and will try to make some suggestions to improve the overall filtering efficiency.
