Do not remove the following line, or various programs

that require network functionality will fail.

++ Configuring Postfix and Dovecot

• Turn off sendmail

service sendmail stop

chkconfig sendmail off

system-switch-mail

(select postfix)

• Configure postfix and dovecot to allow the creation of mail subfolders

postconf -e 'home_mailbox = Maildir/'

• Edit /etc/dovecot.conf and add the following to the end of the file:

mail_location = maildir:~/Maildir

namespace private {

separator = /

prefix = ""

inbox = yes

}

• Add the following to /etc/dovecot.conf to enable the IMAP protocol:

protocols = imap

• To configure the rest of postfix, take a look at this nice tutorial:
