As you said: Typically this is a DNS issue in combination with the FQDN
of the site and the Email Server Aliasses.

Things to check:

1.) Sitename: In this example I assume it is www.company.com.

2.) Email Server Alias: There should be only one, named "company.com".
Clear this field out, save the changes and put "company.com" back in.
Only that - no more. Then save once more.

3.) DNS:

If you have the following DNS records (no more and no less) it simply
ought to work:

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

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

(**) = In order to do your own reverse DNS your ISP must have granted you
Reverse DNS delegation authority and/or must have slaved your DNS servers.

More "Email Server Aliasses" and more DNS A and MX records are possible,
but for sake of simplicity I'd suggest to just try the above
minimalistic settings.

Other things to check:

After you saved the "Email Server Alias", Sendmail should have been
restarted. For good measure restart it manually as well: "service
sendmail restart".

Check "cat /etc/resolv.conf" to see which DNS server your BlueOnyx is
using. Maybe it is using a DNS server to which these changes haven't
propagated yet.
