I have a test server I am using to learn how to set up and configure different set ups in Linux. I got mostly everything working but I am trying to set up mail services on the server and seems to be having a really hard time in doing so. This is what I have done so far.
When I first started, I was told I could use Dovecot and Exim to do what I needed. I looked up how to configure them and spent days trying to get it working but nothing. I tried to connect with Roundcube and it does not work and I get the following error:
Connection to storage server failed.
I was then told to remove Dovecot and Exim and use Postfix but still getting the same error.
I just have one domain name on the server and I want to send e-mails from the server and receive e-mails to that server with the domain name firstname.lastname@example.org
ANY help even small would be GREATLY appreciated as I have been lost for days.
