UNIX for Dummies Questions & Answers

hi guys

I have to configure a SMTP server using Postfix, ok let me tell the domain is located at godaddy so my smtp postfix server has to use that domain let's say mycompany.com

so anyone knows how to configure postfix using this way?
or postfix is easy to configure?

thanks a lot

If it is easy or not depends on if you have simple demands or not. What exactly did you expect to get as an answer? And what exactly are we supposed to tell you knowing only your desired domain name?

I suggest you get some how-to (introduction documents) for Postfix, read it and then start working. If you have a real question we might be able to answer it, but right now your "question" amounts to: can you do my work for me. The answer to that is: yes.

well I already configure postfix following this guide

Postfix Mail Server Configuration

my doubt is that my customer says that I have to include accounts in my email configuration

he says I have to include

service_support@companyname.com
it_support@companyname.com
and so on like 6 accounts

and checking the postfix configuration

Code:

mydomain = example.com 
myorigin = $mydomain 
myhostname = mail.example.com
mydestination = $myhostname, localhost, localhost.$mydomain 
mynetworks = 192.168.3.0/24 
inet_interfaces = all

I have no idea where to put those

thanks

but I am not able to reply to the address adminit@companyname.com

I get this

Delivery to the following recipient failed permanently:
adminit@companyname.com
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 #5.1.0 Address rejected. (state 13).

Does user adminit exist at companyname.com? Entering it as MAIL FROM address doesn't mean it does, does it?
