Hello all, I've just freshly registered to this community, couldn't find a proper introduction forum so I'll just post something nice here. I am a Dutch student at the Rotterdam University studying to become a teacher, I love photography and always shared a passion with anything IT-related. This passion brought me the idea to host a website myself, something which I've been doing successfully for some time now. I felt it was time to get a bigger project started so I bought a domain-name and wanted to see what kind of 'cool stuff' I could do with it. The basic concept what I have now, is just to host "a bunch of websites" be it Wordpress, Joomla! or Drupal anything and everything just as a huge experimentation. To cut a long story short, I followed this excellent tutorial: http://www.howtoforge.com/perfect-server-ubuntu-10.10-maverick-meerkat-ispconfig-3 to the letter, copied and pasted as much as I could and trying to Google what the heck I was exactly doing. Now, one of my greatest desires is to have my own mail-server, so being able to send and receive mail to other domains. As I said, I followed the tutorial to the letter, and made some quick configurations in ISPconfig. However, I don't have the ability to receive or send mail to domains outside my own, I've taken it upon myself to start a new leaf, format and start over. For this to be successful I have a few enquiries which I hope people will be able to help me with. I have the ability to change my DNS settings by a third-party provider, I've deleted all the records, save for two: Code: A brothersonline.nl → A localhost.brothersonline.nl → 127.0.0.1 CNAME www.brothersonline.nl → brothersonline.nl Starting a new leaf, first things first, how should I name my server? The first time I went through the guide I choose server1.brothersonline.nl is this suitable or should it be (e.g mail.brothersonline.nl) I know I have to make an MX-record to whatever my mailserver is, so this will likely be: Code: MX-xx brothersonline.nl --> xx.16x.2xx.xx To send mail to certain hosts, gmail in particular, I probably should create a PTR record too, my DNS provider allows me to create a PTR record. so this should probably be: Code: PTR brothersonline --> xx.16x.2xx.xx When we're done with that, I will resume my guide. After I am done, how do I configure my mail-server to receive and send mail to other domains? I received this error everytime I tried to send a mail to email@example.com Code: Delivery to the following recipient failed permanently: firstname.lastname@example.org Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 <email@example.com>... Relaying denied (state 14). ----- Original message ----- Received: by 10.216.162.84 with SMTP id x62mr3805903wek.106.1296284765224; Fri, 28 Jan 2011 23:06:05 -0800 (PST) MIME-Version: 1.0 Sender: xxxxxxxxxxxxxxxxxxx Received: by 10.216.23.20 with HTTP; Fri, 28 Jan 2011 23:05:45 -0800 (PST) From: xxxxxxxxxxxxxxxn <xxxxxxxxxxxxxxx> Date: Sat, 29 Jan 2011 08:05:45 +0100 X-Google-Sender-Auth: CiqsmDbD3LQsVFZYaNHeIu2E1R4 Message-ID: <AANLkTi=SLxhqLsBAA97n5mOUcAQWTrGfHfQ=2hcgWfirstname.lastname@example.org> Subject: test To: email@example.com Content-Type: multipart/alternative; boundary=001636458010f58022049af6d0b2 I've also tried sending e-mails to: firstname.lastname@example.org and email@example.com. I'm pretty new to this level of hosting, and I know I might be lacking some basic understanding, but I am dead in the water about now, so if anybody could give some pointers, be it explanations or just even hints, I will gladly try to follow up on them and see if it fixes my particular problem. Thank you kindly for any help you might be able to provide me with.
