Some scanners also automatically enable an Internet protection feature. If the virus scanner does not have the facility to exclude the appropriate folders, you must disable on-access scanning completely for that scanner. You must exclude these working folders even if you do not configure MailMarshal to scan for viruses using the antivirus product. To prevent scanning these working folders, you must configure your scanning products to exclude specific working folders on every MailMarshal Server. MailMarshal will not operate if these folders are scanned by an antivirus or anti-malware product. MailMarshal uses a number of folders to process and quarantine email messages, possibly including virus infected messages. Then, you must configure MailMarshal to use the antivirus product you installed.ģ.8.1 Excluding Working Folders From Virus Scanning The MailMarshal Engine service does not run if an antivirus product scans these folders. To allow MailMarshal to use your antivirus product to scan email for viruses, first exclude specific MailMarshal folders from virus scanning.
