[IMail Forum] New user setup questions

[Joe Halloran]

Pardon my greenness - we just got our dsl connection and I am now trying to get imail to talk to the rest of the world.  Current set up is as follows:   We are using our isp's dns servers.  The isp has filled out the mx record at his place to point to our internal ten net ip via our router - I think the router does the final address translation to the ten net ip.  When I try to send mail via the imail smtp server I get this error:   "The message could not be sent.....rejected by the server.  The rejected email address was ................, Server Response: 550 not local host.... not a gateway........"   If I send mail to the imail server via the isp's smtp server it does come back in - I need to test whether it will come in from another isp (send me a message at [EMAIL PROTECTED] if you want to help me test!!).   Some test messages that I sent earlier seem to have gotten thru - at least the header reports that the targer received it from our imail smtp server.....but now all is error.   So - any leads, hints, clues or outright solutions much appreciated!   Joe Halloran
