Hi,

I would like to setup an email system for my team on local network. May I know if it is possible to setup a email server on one machine, and the other machines will just send and retrieve emails from this server remotely? Or I will need to setup individual email servers on each machine?

In the former case, does that mean for the email address, it can be xxx@aaa.bbb.ccc or yyy@aaa.bbb.ccc, but for the latter case, the email address will be xxx@aaa.bbb.ccc or yyy@ggg.iii.hhh?

Also can advise how can I setup the email server in RHEL 6?
I'm a newbie and I don;t quite understand the concept of the email server.

Thank you.

Hello,

As you said you are new to linux then I would suggest you to go through these links , so you can have better understanding of how to configure a mail server.

I would make sure you have the netfilter configured correctly before you start configuring for email.

You want to make sure you use pop before smtp as well, also I would recommend using TLS, if you do this you will need SSL certificate on your server(s).


Email servers can be a nightmare to manage if you do not get a good start out of the gates. Plus, you do not want to get on blacklist.

Hi shertay

If you want a Mail server "out of box" setup you can try iRedMail for start and then further on configure settings to your own needs.

THANKS for the link on iredmail!

I am going to check it out.

Hi,

What if now I would like to configure my email server (domain: aaa.bbb) to send emails for another domain (ccc.ddd). How should I go about doing it?

E.g. Domain aaa.bbb has this list of users and domain ccc.ddd has another list of users that are exclusive of each other, and I do not wish to create users of domain ccc.ddd in domain aaa.bbb.

Is it something related to the virtual mailbox domain? or virtual alias domain? But do I have to list all the users in domain ccc.ddd in the /etc/postfix/vmailbox on how to handle the mails? But I would like to direct any emails to <anything>@ccc.ddd to the ccc.ddd email server from the aaa.bbb email server, and vice versa.

Thank you.

You're getting far too complex too soon. You want your mail server (aaa.bbb) to relay email for domain (ccc.ddd). Before you start getting crazy with how to relay domains, I strongly suggest you find an old junk PC and load Linux on there. After that, load Postfix for MTA (sending email) and Dovecot for retrieving email (MAU). There you will learn so much about email, it will blow your mind. Set up sender / client access lists, user accounts, quotas, and other filtering rules. Mail servers are nothing more than routers...nothing more.
