Question on Sendmail


I have been slowly milling through the process of learning some sendmail. I would like to verify something regarding its capabilities.

I know if I have a domain MYDOMAIN.COM I can have username@MYDOMAIN.COM. If I also have MYSECONDDOMAIN.COM I can have mail going to that too as username@MYSECONDDOMAIN.COM.

What I think I am understanding now, and steer me in right direction if I'm off, is that *username* is the same account?

If my friend JOE has an email account/user account on my sendmail box called "joe" then, if I send mail to joe@MYSECONDDOMAIN.COM or joe@MYDOMAIN.COM the mail goes to the same place.

I can't have one machine running sendmail have different accounts for username@MYDOMAIN.COM? and username@MYSECONDDOMAIN.COM?

What I was looking for was ONE BOX that could handle email for domain1.com, domain2.com, domain3.com, etc but not have them intertwined. I may be confusing the matter more here with how I wrote this but hopefully you understand what I mean.

I'm just wondering if I needed to have a separate sendmail box for each domain I wanted to have full featured email capabilities.

I don't know what version you are using but I';ve been usig a GUI called Webmin, it works for me cause i come from a windows background but in Webmin you can go to the various server settings and create the domains for which you want to recieve email on. Then its just a matter of entering the accounts in 'webmin users' and you're away. Joe is probably doing it that way so an email to anyuser@mydomain.com or anyuser@mydomain2.com will be forwarded to his computer if he's set his domains as mydomain.com or mydomain2.com.

SO the answer to your question is yes, you can have separate domains handled by the one machine for email. You would need to set up postmail to handle logs for each I think. I run 4 domains at work without a problem, except for the one I have at the moment that confuses the hell out of me. See my post re: email attachments not recieved

I don't at all profess to know Linux well so if i have forgotten anything please add to my comments

I have webmin, but I believe for me I would like to learn the command line way of configuring things before I go the easy route. Im not saying this is how it should be for all. Just for me. I enjoy command line work -- sometimes -- MY background is in windows, thats where I make my living. Linux for me is for fun, or small projects that are personal, sometimes for work as well. I can see where email could be a good option for linux in a business environment for me. Plus you can't beat the price. I love open source :-)

Once I get a better grasp of how to do things via the CLI, then I plan on using tools like webmin for often. I have it installed now, and look at it now when working on learning new things but my main way of entering a project is via the CLI and SSH.

Red Hat's website has some decent docs that are easy to read. Here is a link to their Sendmail how-to.

http://www.redhat.com/docs/manuals/l...-sendmail.html

There is also one on Tripwire that is easy to understand. You might want to install that on your system too, since it is running a public service.
