I have RT configured on my CentOS 5.5 box, help.domain.com. My /etc/alias file uses <a href="mailto:help@help.domain.com">help@help.domain.com</a> for incoming requests into my main helpdesk queue. What I’ve done with Exchange, that hosts for domain.com, is to create the email <a href="mailto:help@domain.com">help@domain.com</a>, and a contact for <a href="mailto:help@help.domain.com">help@help.domain.com</a>. The newly created Exchange mailbox, <a href="mailto:help@domain.com">help@domain.com</a> forwards to <a href="mailto:help@help.domain.com">help@help.domain.com</a>. What this allows me to do is use delivery restrictions on the Exchange account to limit the help desk to authenticated users only, thus blocking outside requests. I know RT has it’s own mechanism to do this, but this allows me to open it up easily if I need to, and I can use LDAP authentication alongside local users in RT.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div><BR>
