The installation program automatically configures Microsoft Internet Information Services (IIS ) 5.0 or later.
An IIS configuration file, Web.config, is installed during the installation routine. A file attribute, maxRequestLength, in the Web.config file is set to 102400 KB (100 MB). This attribute sets the maximum amount of data that can be uploaded using IIS.
Important: We recommend that you do not change the value of the maxRequestLength attribute in the Web.config file and that you manage the Max. Outbound Message Size and Single Message Maximum Size in the Domain Properties page of the Web Administrator. For more information, contact your email administrator.
