with only $ at the end this rule will not work at all, because filename is placed between “”, so all line looks like follows:
/name=[^>]*\.(bat|com|exe|dll|vbs)\”$/ REJECT

Can I do this only for a user list or a group? This is a global setting which is applied to all users. If its possible, please send some guidelines.

If you use this rule, you may have problems with the emails, which has attachments containing a website adress in file name. For example: "yahoo.com statistics.xls" I use /name=[^>]*\.(bat|com|exe|dll|vbs)$/ REJECT to fix this issue :)
