Question: xFusionCorp Industries has planned to set up a common email server in Stork DC. After several meetings and recommendations, they have decided to use postfix as their mail transfer agent and dovecot as an IMAP/POP3 server. We would like you to perform the following steps:
Install and configure postfix on Stork DC mail server.
Create an email account ammar@stratos.xfusioncorp.com identified by B4zNgHA7Ya.
Set its mail directory to /home/ammar/Maildir.
Install and configure dovecot on the same server.
1. Login on the Mail server as per the task and switch root user
thor@jump_host /$ ssh groot@stmail01 The authenticity of host 'stmail01 (172.16.238.11)' can't be established. ECDSA key fingerprint is SHA256:SySamszyWhhLGFiybhGBqfrr8g55wS/3e37ZpBOvICs. ECDSA key fingerprint is MD5:6d:31:18:2a:f9:07:f3:29:dd:0a:d3:1f:6e:04:0a:db. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'stmail01,172.16.238.17' (ECDSA) to the list of known hosts. groot@stmail01's password: [groot@stmail01 ~]$ sudo su - We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: #1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility. [sudo] password for groot: [root@stmail01 ~]# |
2. Install the packages Postfix & Dovecot

ReplyDeleteThanks for your kind words.. Keep Learning
DeleteThank you for this page. It helps. Suggestion: for a video like this, I think it is important to add voice. For instance, where did you get the cidr numner you used in the /etc/postfix/main.cf. Also, we would like an explanation of each changed line in the main.cf file.
ReplyDeleteIndeed , intention not to add voice was for self learning & troubleshooting task by your own. CIDR you get form the host by running ifconfig. Sure will try to post soon explanation of each changed line. Feel free to connect me for any help or support required. Keep Learning
DeletePlease, I would like to learn more from you. Can we connect over LinkedIn at www.linkedin.com/in/magamudi.
ReplyDeleteI also feel like this video should have a voice to explain the process and why we are making the changes in the configuration file at /etc/postfix/main.cf. Lastly, I would like to know where you got the cidr number you used in the mynetwork line in the conf file.
Thanks for your kind words. Sure I wont mind to teach you , but due to the current work commitment I cant commit you time. For Now you can ping me online support chat or drop email id will revert with solutions
DeleteHello! Dont forget to uncomment Mode = 0666
