UNIX for Dummies Questions & Answers

Folks;
I want to give a group a read access to a directory tree, but i want the group to be defined by the email account. here's the details:

I have a punch users who use e-mail addresses of "*@blue.com".
I want give this group of "*@blue.com" a read access to a directory tree so every one who has "user_name@blue.com" will be able to read any files under this directory /opt/dirs/

BTW: I couldn't find ".mailrc" on my Solaris 8 to add aliases

Any help will be appreciated

Do these people have logins on this server?

No, that's why i need to use the group by e-mail so i can allow any user who
part of this email address can read the files under the directory

How are they going to read that directory? What application, tool, protocol etc?

The directory is located on UNIX server & has punch of web applications & html files. there's a link can be opened through any web browser to access these web pages & directory contents
I want these users to be able to access these web pages & the directory contents when they click on the link

Some information might be useful, such as the platform you are running on and the web server you are using.

Actually this is an access control issue ( i believe related to Apache) & i want these users whos email under "*@blue.com" to be able to access this webpage with all its contents

This is Apache 2.0 running on Solaris 8
