mail aliases to be restricted to use within internet domain
Posted on 2003-11-21
We have an IBM server with Linux op. System (Redhat ver 8.0). This server has been configured as mail server using sendmail. I have difined the aliases in /etc/aliases (which become part of aliases db in /etc/mail/aliases. These are working ok but the problem is these can be used by OUTSIDERS also.
I am looking at the documentation but if some one knows how to restrict the mail aliases to LOCAL use (use within our mail server or within our internet domain), please let me know, Thanks
