Thanks for reply - the routing page shows some limits on who can reroute via the smtp - but as I understand it that only applies to routing to foreign domains, not to inbound traffic. On the connections page I just have the address of our isp as a forwarder - all mail goes out fine so we're sure that works. Our isp has the address of our router which uses NAT to translate to the mail server - again this bit must work as the smtp protocol log shows various internet mail servers trying to connect - the only bit that's not working seems to be the return path so the imc can respond with an acknowledgement and start receiving the message. The imc does respond to hosts inside the network using it as an smtp server to reroute out to internet which is the same sort of thing as this mail comes inbound first before being rerouted.
Let me know if you think of anything I'm missing - I've got a nagging doubt that it may be DNS settings on the mailserver or something...
