Hi,
 
 fairly new to setting up email servers and im 
 currently just playing about with ip addresses 
 for servers instead of actual domain names. 
 
 If i setup my smtp server i am able to send 
 emails out using my local ip address of my 
 server eg.192.168.0.1 but from within that 
 same location i cant use the external address 
 on the internet eg.10.10.10.90. I can also 
 send emails if im at another location and 
 point it to the external ip but i guess there 
 is some conflict when using the external ip 
 when behind that actual ip address.
 
 Maybe i need to use a proxy server but i was 
 hoping there would be an easier way round it. 
 
 Hope you can advise.

If you need to send mails through your SMTP server to external recipients, you need to configure DNS (create MX and PTR records). External SMTP servers will reject your messages until you create MX and PTR records for your SMTP server.
 
 Best regards,
 Andrew
