Existing problems and their solutions

• 30100 Content filtering can be applied only to the smallest parts of a message. It means that you can delete only a part that coincides by content-type, but not all parts of a message. Consequently, if content filtering rule coincides with any part similar to ‘message/*’ and ‘multipart/*’, the action will not be performed and a warning message will be added to the report.
• 38728 The kavscanner utility uses the full file path, so if there are too many subdirectories, an error message appears due to line length restrictions. The full file path should not exceed 4096 bytes. Objects located in deep nesting levels, will not be scanned.
• 40009 The kavscanner utility can not scan some file types if their size exceeds 2 GB.
• 40835 After Kaspersky Anti-Virus for Linux Mail Server integration with Sendmail, Kaspersky Anti-Spam 3.0 loses integration. After installation it is recommended to integrate Kaspersky Anti-Spam again.
• 40853 After integrating some Exim versions with Kaspersky Anti-Virus for Linux
  Mail Server via dl_func failures may happen. It is connected with Exim error. For more information, please refer to http://bugs.exim.org/show_bug.cgi?id=713.
