Netscape v4 and above also consults the extension mappings, but I believe it relies on mime type first and only when it can't find the right mime type does it look at the extension. Example: Malconfigured webserver servers *.htm files up as application/octet-stream. Netscape looks at the mime type and shows the data as plain text, IE (which outlook uses) looks at the extension, and parses the contents as HTML. So, in short: You need to filter both file extensions and mime types. This goes for all file types on Microsoft platforms (and quite possibly a few other platforms aswell?). $.0002 /Mike -- Mikael Olsson, EnterNet Sweden AB, Box 393, S-891 28 �RNSK�LDSVIK Phone: +46 (0)660 29 92 00 Direct: +46 (0)660 29 92 05 Mobile: +46 (0)70 66 77 636 Fax: +46 (0)660 122 50 WWW: http://www.enternet.se/ E-mail: [EMAIL PROTECTED] - [To unsubscribe, send mail to [EMAIL PROTECTED] with "unsubscribe firewalls" in the body of the message.]
