Configure Evolution(MUA) for root account on Linux

​Tried to configure 'sendmail' and 'dovecot' and tested using command line to send emails by creating couple of local user accounts. Later, for easy access configured 'evolution' mail client.

In brief, here are the changes made on the system while I configured system.

sendmail: 

# yum install sendmail sendmail-cf

# vi /etc/mail/sendmail.mc

​​

From:
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

​​

To
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

​​

​save and quit(:wq)​

# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

# vi /etc/mail/local-host-names

localhost.com

# service sendmail restart

# chkconfig sendmail on

Dovecot:

# yum install dovecot

# vi /etc/dovecot/dovecot.conf

From:

#protocols = imap pop3 lmtp

To:

protocols = imap pop3

# vi /etc/dovecot/conf.d/10-mail.conf

From

#mail_location =

To

mail_location = mbox:~/mail:INBOX=/var/mail/%u

​# service dovecot restart

# chkconfig dovecot on

​Configure your evolution mail client: 

 

# yum -y install evolution

upgrade 'git' to 2.x Redhat/CentOS

Tried to upgrade 'git' to latest as I had few applications which was not supported with older git which suggested me for 2.x. while I, tried to 'yum update git' I couldn't find 2.x being in Redhat/Oracle repository. Later, followed to install manually and these steps were documented below instructions. 

Overview: 

- Ensure your packages are installed(curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker)

- Remove installed 'git' from system

- Download the latest version from kernel.org (I would download git-2.8.6)

- Install git.

- Make sure you add in PATH of your profile.

- Check your 'git' version. 

Steps:

[root@localhost ~]# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker -y

Loaded plugins: aliases, changelog, kabi, ovl, presto, refresh-packagekit, security, tmprepo, ulninfo, verify, versionlock
