When installing on Windows Server 2008, the following pre-requisites are required: • Web Server (IIS) role • ASP.NET • Windows Authentication Services • Microsoft SMTP Services For more information, refer to: http://kbase.gfi.com/showarticle.asp?id=KBID001596 If you are installing on Microsoft Exchange Server 2007/2010, you need to install one of the following roles; • Edge Server Role, • Hub Transport Role or, • Mail Server and Hub Transport roles. GFI MailSecurity cannot be installed on a Microsoft Exchange 2007/2010 machine with only Mailbox Server Role installed. In addition, IIS SMTP service is not required, since it has its own built in SMTP server. When using Small Business Server, ensure you have installed Service Pack 2 for Exchange Server 2000 and Service Pack 1 for Exchange Server 2003. Disable anti-virus software from scanning the GFI MailSecurity directories. Anti-virus products are known to both interfere with normal operation as well as slow down any software that requires file access. In fact, Microsoft does not recommend running file-based anti-virus software on the mail server. For more information, please refer to http://kbase.gfi.com/showarticle.asp?id=KBID001559. GFI MailSecurity directories should never be backed up using backup software.
