Before starting with this post you need to follow the steps which we have followed in the part1
SO Guys lets start with the phase 3
now starting with the phase 3 lets start with the configurations of postfix.
Add hostname entries in /etc/hosts file as shown below:
and same true for 3306 as well.
SO Guys lets start with the phase 3
now starting with the phase 3 lets start with the configurations of postfix.
Add hostname entries in /etc/hosts file as shown below:
# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.101 mail.rathi.com mail
I disabled SELinux to reduce complexity in postfix configuration.
If you want to keep SELinux on, enter the following command in Terminal:
# togglesebool httpd_can_network_connect
Allow the Apache default port 80 and port 443 if you are using ssl and 3306 if your mysql is on another server through your firewall/router:
# vi /etc/sysconfig/iptables
[...]
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
[...]
fowling are optional as they will come in picture if you are using production or more complex setup of more than one server
[...]
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443-j ACCEPT
[...]
Configuring Postfix
Edit /etc/postfix/main.cf,
# vi /etc/postfix/main.cf
find and edit the following lines:
## Line no 75 - Uncomment and set your mail server FQDN ## myhostname = mail.rathi.com ## Line 83 - Uncomment and Set domain name ## mydomain = rathi.com ## Line 99 - Uncomment ## myorigin = $mydomain ## Line 116 - Set ipv4 ## inet_interfaces = all ## Line 119 - Change to all ## inet_protocols = all ## Line 164 - Comment ## #mydestination = $myhostname, localhost.$mydomain, localhost, ## Line 165 - Uncomment ##\ mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain ## Line 419 - Uncomment ## home_mailbox = Maildir/
Save and exit the file. Start/restart Postfix service now:
# service postfix restart # chkconfig postfix on
Testing Postfix mail server
First, create a test user called “nrathi“.
# useradd nrahi # passwd nrathi
Access the server via Telnet and enter the commands manually shown in red colored text.
# telnet localhost smtp
Trying ::1... Connected to localhost. Escape character is '^]'. 220 mail.rathi.com ESMTP Postfix ehlo localhost ## type this command ## 250-mail.rathi.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from:<nrathi> ## Type this - mail sender address## 250 2.1.0 Ok rcpt to:<nrathi> ## Type this - mail receiver address ## 250 2.1.5 Ok data ## Type this to input email message ## 354 End data with <CR><LF>.<CR><LF> welcome to rathi.com mail server ## Enter the boddy of the email ##. ## type dot (.) to complete message ## 250 2.0.0 Ok: queued as B822221522 quit ## type this to quit from mail ## 221 2.0.0 Bye Connection closed by foreign host.
Now navigate to the user “nrathi“ mail directory and check for the new mail:
ls /home/nrathi/Maildir/new/
Sample output:
1390215275.Vfd00Ie04f8M357080.mail.rathi.com
A new mail is received to the user “nrathi“. To read the mail, enter the following command:
# cat /home/nrathi/Maildir/new/1390215275.Vfd00Ie04f8M357080.mail.rathi.com
Sample output:
Return-Path: <nrathi@rathi.com> X-Original-To: nrathi Delivered-To: nrathi@rathi.coml Received: from localhost (localhost [IPv6:::1]) by mail.rathi.com (Postfix) with ESMTP id B822221522 for <nrathi>; Mon, 20 Jan 2015 16:23:54 +0530 (IST) Message-Id: <20140120105404.B822221522@mail.rathi.com> Date: Mon, 20 Jan 2015 16:23:54 +0530 (IST) From: nrathi@rathi.com To: undisclosed-recipients:; welcome to rathi.com mail server
Add the following line at the end.
mailbox_command = /usr/bin/zarafa-dagent “$USER”
Save and close the file. Restart postfix service to take effect the saved changes.
# service postfix restart
The remaining things i will cover in the next part phase 4
