Help for setting up XMail server on a ARM CPU NAS behind a router with firewall

Although I've some experiences in SysAdmin I can NOT get a functional configuration for an XMail server running on a DLINK 327L Network Attached Storage with LINUX. The server is very small and very funtcional (in Intranet) but I've got a problem sending e-mails outside my net. The NAS is behind a Router with internal DSL mode, with SMTP/POP3/Secure Mail ports open (also from outside) with port forwarding. I currently have a domain e.g. named bla.mydom.com, the router has 192.168.178.1 as intranet address, outside address for router is 86.122.98.64, the NAS XMail server has intranet address 192.168.178.32 and has all ports open for mailing (NAS)

Running "tshark" on the NAS server while sending from a client with "Balsa" Mailer to that NAS Mail server I've seen that there is NO MX nslookup/DNS lookups for outside mail servers like gmail.com only for my domain (or eg bogus.com) - but I can eg. ping, nslookup etc. on the shell on that NAS, With Swaks (running on the NAS) sending outside eg. to Gmail it is working

What should I have to do for sending email outside? (I got mad)
