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 protected] Code: Delivery to the following recipient failed permanently: [email protected][email protected][email protected][email protected] I've also tried sending e-mails to: [email protected] and [email protected]. 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.
