| + | ====== Installing Mail Delivery and Cyrus IMAP ====== | ||
| + | |||
| + | # cd /tmp | ||
| + | # mkdir cyrus-imap | ||
| + | # cd cyrus-imap | ||
| + | # wget http:// | ||

| + | # sh cyrus-imapd.SlackBuild | ||
| + | # installpkg / | ||

| + | 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> | ||
| + | localhost> | ||
| + | localhost> | ||
| + | < | ||
| + | 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 / | ||
| + | # cp / | ||
| + | # chown root / | ||
| + | # chmod 400 / | ||
| + | # cp / | ||
| + | Now add the followings to / | ||
| + | smtpd_use_tls = yes | ||
| + | smtpd_tls_key_file = / | ||
| + | smtpd_tls_cert_file = / | ||
| + | smtpd_tls_CAfile = / | ||
| + | <note important> | ||
| + | | ||
| + | -o smtpd_tls_wrappermode=yes | ||
| + | -o smtpd_sasl_auth_enable=yes | ||
| + | </ | ||
| + | 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 / | ||
| + | # rm new.key.pem | ||
| + | # cat ca-cert >> / | ||
| + | # chown cyrus:mail / | ||
| + | # chmod 600 / | ||
| + | # echo tls_ca_file: | ||
| + | # echo tls_cert_file: | ||
| + | # echo tls_key_file: | ||
| + | | ||
| + | ====== 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 / | ||
| + | # Starting saslauthd daemon | ||
| + | if [ ! -r / | ||
| + | echo " | ||
| + | / | ||
| + | fi | ||
| + | |||
| + | # Starting IMAP daemon | ||
| + | if [ -x / | ||
| + | echo " | ||
| + | / | ||
| + | fi | ||
| + | |||
| + | # Starting POSTFIX daemon | ||
| + | / | ||
