Will you be accessing this machine (using the domain name) from within your home private network or from outside public networks ? If its within then a host entry on all the home PC's will do the trick.



If it's on external public networks then you will have to get a registered domain name, have a static public IP for your server machine and then open ports needed for your server application so that it can be accessed publicly.

You can do a simple thing, register with no-ip.org or dyndns.org and set up a hostname for your IP address



If you need more info just ask, I use this option to access my computer from office

Is it a godaddy stuff? If so gtalk with me on myself (dot) linuxtechie (dot) net, I will walk you through it.

Ill be a bit more clearer please help.



1) I have domain name.

2) This has been bought by some company called qualishosting

3) I have a server, which has to act like a SMTP server. Only purpose is to send mails, maybe receive, but mostly send.

4) Thus a server was setup, and using postfix(MacOSX) I have made the SMTP server.

5) I need to modify the DNS records A,CNAME etc etc in order to point to Servers static IP (Static IP is already bought).



@LT I have added u as myself "at" linuxtechie "dot" net. Please accept

If your domain registrar does not support DNS Management, you can use NameCheap's Free DNS It will let you add the necessary DNS records.



Once you have registered for NameCheap Free DNS, just change the nameservers to the ones provided by NameCheap from your domain registrar's control panel.



You need to create two A records pointing to your static IP for domain.com and www.domain.com



Also if the amount of mail is less you can use sSMTP to send mail via GMail, which will give guaranteed delivery to inbox. If sending from your server, the mail may not reach the inbox and can go to SPAM or JUNK folders.

You want your home machine to act like a mail server and you have already configured postfix. Right?



Now you just need to change the MX record of your domain. Login to your domain control panel and look for "Manage DNS" Option. there will find option to edit/add MX records.





Hope it helps

But I dont have domain name pointing to my home server yet, and I need to put a FQDN in my MX Records.



I do have DNS Management, but I donot know what to put where.



OHH and I need to send like 20000 emails per week, so Gmail is out of the question.

Do it then?



* Add a simple A record like mail.yourdomain.com which points to your static IP address.

If you only want to send mails from this server, you don't have to configure the MX records. Also for ensuring proper delivery remember to create an SPF record.



The SPF Setup Wizard

Thats it, I just need to add IP in the A Record. Nothing else?



This is nice. Really appreciate your help. I shall try tomm and let you know.



Could anybody pint me to a website which explains, what all these DNS things mean like CNAME, TLD etc etc? Would like to learn and understand. I tried Wikipedia, but that did not have enough info.

Google and Wikipedia is you friend... Here is a link



Now I guess only 2 tasks are remaining:



1. Make a host A records pointing to your server. Like mail.urdomain.com to ur Public Static IP

2. Make a MX Record for urdomain.com to point to your server's public IP.



and thats it I guess....



Ppl if I have missed anything please add.

Thanks a lot guys. This actually worked. Now to add SPF and DomainKeys and what not.
