makeが正常に終わればインストール。

※インストール時にオプション選択画面が表示されると思いますので
「MYSQL」と「SASL2」を選択しておきます。


インストールが終わると、いくつか質問されますので答えていきます。
===>   Installing for postfix-2.2.2,1
===>    postfix-2.2.2,1 depends on shared library: 
pcre.0 - found
===>    postfix-2.2.2,1 depends on shared library: 
mysqlclient.12 - found
Added group "postfix".
Added group "maildrop".
Added user "postfix".

～[ 質問1 ]～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～
ユーザーとグループの追加するかどうかの質問なのでそのまま[Enter]します。
You need user "postfix" added to group "mail".
Would you like me to add it [y]? [Enter]
～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

～[ 質問2 ]～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～
mailer.confをPosftix用に書き換えるかどうかなのでここは[y]とします。
Would you like to activate Postfix in /etc/mail/mailer.conf [n]? y
～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～～

質問2で[y]を選択すると最後に↓Postfixの起動方法が表示されます。If you have postfix configured in your /etc/mail/mailer.conf
(answered yes to the previous question) and would like to enable
postfix to start at boot time,please set these variables in your
/etc/rc.conf file:

This will disable Sendmail completely.

Alternatively to the above settings, you can enable postfix to
start with the other local services, for example, after your
database server starts if you need it to be running for postfix.
To do this, set in your rc.conf file:

sendmail_enable="NO"

Then make the following symbolic link:

cd /usr/local/etc/rc.d
ln -s /usr/local/sbin/postfix postfix.sh

Also, you will want to disable some Sendmail-specific daily
maintenance routines in your /etc/periodic.conf file:

daily_clean_hoststat_enable="NO"
daily_status_mail_rejects_enable="NO"
daily_status_include_submit_mailq="NO"
daily_submit_queuerun="NO"
 ↑ここまでを記述。


If you are using SASL, you need to make sure that postfix has
access to read the sasldb file.  This is accomplished by adding
postfix to group mail and making the /usr/local/etc/sasldb*
file(s) readable by group mail (this should be the default for
new installs).

If you are upgrading from postfix version prior to 2.0, please
see the README files for recommended changes to your
configuration.

オプションは「AUTH_MYSQL」を選択しておいてあとはデフォルト。

makeが正常に終わればインストールします。
# make install


In case you use authpam, you should put the following lines in your 
/etc/pam.conf
pam認証を使う場合はこの3行を"/etc/pam.conf"に追加する。
imap   auth      required   
pam_unix.so    try_first_pass
imap   account required   pam_unix.so    
try_first_pass
imap   session  required   pam_permit.so

You will have to run /usr/local/share/courier-imap/mkimapcert to 
create a self-signed certificate if you want to use imapd-ssl.
And you will have to copy and edit the *.dist files to * in 
/usr/local/etc/sourier-imap.
