The server sits on a private network and is being NATed to the outside. The adsl router is doing this Netcomm NB1400. Inbound I have let 110/tcp and 25/tcp through. I have told the router which machine to resolve these packets to which is my mail server. Anything can get out.
Sorry about being a bit security consicene. But if you would like to try the ip of the machine in question (well the IP I have being assigned) 203.219.50.38. You well get through on port 110 but not 25. I was doubtful of the DNS. There is another worry in that I can send mail to this address and it seems to disappear into a black hole there is no bounce! Thankyou for all of your replies.I will try the suggestions tomorrow. Jeff -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
