    Hi folks,

    I'm building a LAMP server on Ubuntu 6.05 drake amd64 running local IP w/o ports forwarded to this IP address.

    After finishing installing Postfix mails can be sent to Internet on the server. But it can't receive mails from Internet if w/o port 25 forwarded to its IP address. I can't figure out why it can send mails w/o port 25 forwarded but not the other way round. Please shed me some light. TIA

    w/o = without ???

    ok you need port 25 open ... so the remote mail server can connect and talk to your mail server
    find the user
    than send email over

    like you can access ftp/http without having them open
    but the remote server needs them open to be able to get connection .. hope it help a tab :)
