So were you successful in accessing via IP? If not then you have a firewall problem on the server itself, try disabling the firewall completely. If connecting by IP did work then you need something to help resolve internal addresses. When this is needed I always build a second Bind box that only answers internally. The one accessible to the outside world resolves names to outside IP's, the other resolves the same name to internal IP's. Then I point the DNS for all my internal machines to the internal DNS server. This to me is easier than managing hosts files on all internal machines. The other option is to add the info to hosts files such as: int.ern.al.add mail.yourdomain.com This works good for testing as it is quickly done and easily changed. You have a few problems here from what I see. First test everything locally on the server (send mail, receive mail, telnet to port 25, etc), once that is working then test everything from a workstation on your internal subnet. Once you can perform all tasks internally, then test from your laptop externally. This sequence first let's you know the server is set up right, then helps you troubleshoot connecting a local machine and setting up so your internal network can communicate (troubleshooting mynetworks setting and server firewall). Then you test externally troubleshooting your external firewall and smtp auth/relay settings. I find that to be the best method. Don't forget to re-check in that order as well when making changes as it is easy to break previously tested settings when making firewall changes or changes to the main.cf. Also run "postconf check" after every modification to the main.cf file, this will ensure there isn't any real stupid typos in the main.cf.
