Problem:
(public)
Solution:
(public)		 All sites on a RaQ or BlueQuartz are named in the fashion <hostname>.<domain>.<extension>

Example:        www.company.com

The thing here is that all mailboxes on the server also follow this naming scheme and the correct email address for a user is:

                        <username>@<hostname>.<domain>.<extension>

Example:        test@www.company.com

Obviously one would desire that emails sent to test@company.com (omitting the hostname "www") should also work.

To achieve this and to make sure that emails to test@www.company.com AND test@company.com both get delivered, one has to do the following:


a) "Web Server Alias" & "Email Server Alias":

In the GUI go to the "Site Management" of the site in question.

Click on "Site Settings".

There you see two input textfields labled "Web Server Alias" & "Email Server Alias". On a Sausalito powered server the "Email Server Alias" entry can be found under "Services" / "Email" for the site in question.

If the site is named "www.company.com", then your aliases (both "Web Server Alias" & "Email Server Alias") should be "company.com".


b) DNS:

Next go to the GUI pages for the DNS. On a RaQ3 / RaQ4 that is "Server Management" / "Control Panel" / "Services" /  and "Parameters" behind "Domain Name System (DNS) Server". On a Sausalito powered server that's "Server Management" / "Network Services" / "DNS".

Here is the minimum of DNS records you should have on a server appliance for each site:

 company.com
 ---- A Record ---->
 <IP-Address>
 www.company.com ---- A Record ----> <IP-Address>
 <IP-Address> ---- Reverse ----> company.com
 company.com ---- MX Record ---> www.company.com (*)
 www.company.com ---- MX Record ---> www.company.com (*)

(*) = This MUST be the exact name (including the hostname part) of the domain as shown in the GUI interface.


Summary:

"Web Server Alias" & "Email Server Alias" must be defined, DNS for the domain needs two MX records which point to the full host- and domain name of the site.

This is ONE approach that works. There are others, which may work as well, but usually involve setting up extra MX and A record for something like mail.company.com. This approach here is generally more simple and straightforward.
