 +  # cd /tmp/cyrus-imap
 +  # groupadd -g 238 cyrus
 +  # useradd -d /var/imap -s /bin/sh -u 238 -g 238 cyrus -G mail 
 +  # sh cyrus-imapd.SlackBuild

 +  # su - cyrus
 +  # /usr/doc/cyrus-imapd-2.4.12/tools/mkimap
 +  # su - root
 +Edit /etc/imapd.conf and add the following lines:
 +  sasl_mech_list: PLAIN LOGIN
 +  allowplaintext: yes  
 +Edit /etc/postfix/main.cf and at mailbox_transport add the following:
 +  mailbox_transport = lmtp:unix:/var/imap/socket/lmtp
 +The last step to do is to add users to your imap server. For that you need to issue these commands :
 +  # passwd cyrus
 +and add a password for cyrus user
 +  # cyradm --user cyrus --server localhost --auth plain    
 +  localhost>cm user.slackware_user 
 +  localhost>lm
 +  localhost> quit
 +<note>slackware_user is the user you have created in your slackware machine</note>  
 +At this point we have an functional Mail Server but with users authenticating in plain text . So the next step is innevitabile.
 +
 +====== SSL / TLS Postfix and Cyrus ======
 +
 +Let's start by creating our certificates and configuring POSTFIX to use STARTTLS.
 +  # cd /etc/ssl
 +  # misc/CA.pl -newca ( complete all entries)
 +  # openssl req -new -nodes -keyout mailkey.pem -out mailreq.pem -days 36500
 +  # openssl ca -out mail_signed_cert.pem -infiles mailreq.pem
 +  # cp /etc/ssl/mailkey.pem /etc/postfix
 +  # cp /etc/ssl/mail_signed_cert.pem /etc/postfix
 +  # chown root /etc/postfix/mailkey.pem
 +  # chmod 400 /etc/postfix/mailkey.pem
 +  # cp /etc/ssl/demoCA/cacert.pem /etc/postfix
 +Now add the followings to /etc/postfix/main.cf :
 +  smtpd_use_tls = yes
 +  smtpd_tls_key_file = /etc/postfix/mailkey.pem
 +  smtpd_tls_cert_file = /etc/postfix/mail_signed_cert.pem
 +  smtpd_tls_CAfile = /etc/postfix/cacert.pem
 +<note important>In /etc/postfix/master.cf delete the "#" sign from smtps and the next two columns from it
 +                   smtps     inet  n                               smtpd
 +                     -o smtpd_tls_wrappermode=yes
 +                     -o smtpd_sasl_auth_enable=yes
 +</note>
 +Now let's configure IMAP to use STARTTLS
 +  # openssl req -new -nodes -out req.pem -keyout key.pem  
 +  # openssl rsa -in key.pem -out new.key.pem
 +  # openssl x509 -in req.pem -out ca-cert -req -signkey new.key.pem -days 36500
 +  # cp new.key.pem /var/imap/server.pem
 +  # rm new.key.pem
 +  # cat ca-cert >> /var/imap/server.pem
 +  # chown cyrus:mail /var/imap/server.pem
 +  # chmod 600 /var/imap/server.pem 
 +  # echo tls_ca_file: /var/imap/server.pem >> /etc/imapd.conf
 +  # echo tls_cert_file: /var/imap/server.pem >> /etc/imapd.conf
 +  # echo tls_key_file: /var/imap/server.pem >> /etc/imapd.conf 
 +  
 +====== Adding daemons to rc.local ======
 +  
 +Now the last step is to add all daemons to rc.local so they can start when machine boots. So open /etc/rc.d/rc.local and add these lines :
 +  # Starting saslauthd daemon
 +  if [ ! -r /var/state/saslauthd/saslauthd.pid ]; then
 +      echo "Starting SASL authentication daemon:  /usr/sbin/saslauthd -a shadow"
 +      /usr/sbin/saslauthd -a shadow
 +  fi
 +
 +  # Starting IMAP daemon
 +  if [ -x /usr/libexec/cyrus/master ]; then
 +      echo "Starting Cyrus IMAP daemon:  /usr/libexec/cyrus/master"
 +      /etc/rc.d/rc.cyrus-imapd start
 +  fi
 +
 +  # Starting POSTFIX daemon
 +  /etc/rc.d/rc.postfix start
 +
