    I setup a site and created a email account. I sent email to my hotmail address and it told me it sent the email, but I did not receive it. Then I went to my hotmail account and sent it and received it in the new email account I created. Can you please let me know what to check? I am getting ready to install a php script and want to use the mail for the site. I a a bit new to much of this. thanks for the great info as always.

    Also I had not created a spf record for the mail. I created on with the spf wizared on the noip.com site. I don't understand the port 25 error in the log. I have opened ports 110 and 25 for the mail on my router.

    example.com

    I do not own example.com. can you please send me info on were and how to change this. Do I change it to the domain of the server? (the name I entered when I set up the server.) or do I change it to the domain of the site I am creating in ipconfig? I checked with blacklist. He told me if I have not sent out mail from the server then I can not be on a blacklist. I have never recived mail from any of the mails I have sent from the server. Maybe it is because of this example.com issue. Thanks for your help.

    change hostname

    I am using Debian. I went with Debian because I was having people trying to brute force the box, but I can not get fail2ban to work on the server. I was wanting to do a diffrent setup before I install this script. What one do you recommend for amatures to use? Something were there is some kind of software to stop the brute force. and is there a way to have graffics set up so I can work in graffic or the console?
    It is on a blacklist. I think it is because of the dynamic ip. I will have to change that after I reload or use a working external email account.

    You could try DenyHosts then: http://www.howtoforge.com/preventing_ssh_dictionary_attacks_with_denyhosts (but it'S for SSH only)

    Almost all dynamic IP addresses are blacklisted nowadays. You could relay your emails through another mailserver then: http://www.howtoforge.com/postfix_relaying_through_another_mailserver

    good info

    If I set up the mail like this, will it show as the domain on the receiving end([email protected])?

    Relaying doesn't change the sender or recipient addresses.

    reason for example.com

    I figured out why my mail was saying example.com. On the install (Debian ferfect setup) on the mail, there is a string to be entered. I was not aware I was suppose to change it to my domain. Might want to make a note next to it for people like me. thanks
