squirrelmail
本ページは 2011-07-12 更新されました
Speedex サーバーのサポートを行っている当職は、非常に多くのメールを扱っており、それらを廃棄できない立場にあります。ローカルな環境では Windows7 上で Widows Live Mail を利用していますが、件数が多く、フォルダー構造も複雑になっているためか、頻繁に障害が発生しています。
社内での情報の共有にも配慮し、webmail との併用を検討してみました。
CPX で webmail が使えますが、メールのボリュームが CPX で扱える範囲を超えています。Google Apps の採用も有力だったのですが、将来、サーバー上でメールデータを様々に加工したいこともあり、自由に使える squirrelmail をテストしてみました。
squirrelmail (すくいれるめーると読みます)は SquirrelMail プロジェクトチームが開発している GNU General Public License ライセンスのソフトウエアです。（squirrel はリスのことで画面にもリスのマークが使われています）
上記の目的のため以下条件でテストしました。
- POP3/IMAPに対応したメール配送エージェントとして Dovecot が採用されているため、v3 Linux を使うことにしました。
- php5.3 を vinstall しました。
php5.3 vinstall 手順 - コントロールパネル CPX を uninstall しました。
CPX uninstall 手順 - mbox 形式ではなく Maildir 形式を採用しました。
Maildir 形式設定手順 - Dovecot の設定を変更しました。
Dovecot 設定変更手順 - メールユーザーを作成しました。
メールユーザー作成手順 - VirtualHostを設定しました。
VirtualHost設定手順 - SquirrelMail をインストールしました。
SquirrelMail インストール手順 - SquirrelMail にログインし送受信テストを行いました。
SquirrelMail 送受信テスト
# vinstall php5.3
オプション選択で IMAP support, Multibyte String Functions, OpenSSL Functions, Session Handling Functions, Zip File Functions, Zlib Compression Functions を選択しました。
vinstall 完了後、
# vi /usr/local/php5/lib/php.ini
で、short_open_tag = on に変更。
完了後、
# restart_apache
で、Apache を再起動。
# vuninstall cpx
Maildir 形式設定手順
sendmail は Maildir 形式に対応していませんが、VPS では localmail に procmail を使っていますので、/etc/procmailrc に以下のように設定します。
DEFAULT=$HOME/Maildir/
ドメインによっては mbox 形式を使い続けたいという場合は、/etc/procmailrc ではなく、SquirrelMail を使うユーザーごとにホームディレクトリ内の .procmailrc に上記の設定を行います。
Dovecot 設定変更手順
Dovecot の設定ファイル /etc/dovecot.conf を以下のように編集します。
mail_location = maildir:~/Maildir imap_listen = * pop3_listen = * imaps_listen = * pop3s_listen = *
ドメインによっては mbox 形式を使い続けたいという場合は、mail_location = maildir:~/Maildirの記述は行わないでください。mail_location を Dovecot が自動判定します。
メールユーザー作成手順
コントロールパネルが利用できないので、vadduser コマンドでユーザーを作成、virtusertable、でメールアドレスの登録、転送設定がある場合は、aliases に転送設定を登録します。
以下は info@*******.jp のメールアドレスを使う test ユーザーを作成した場合の例です。
aliases に転送設定が必要な場合は適宜設定してください。
# vadduserPlease supply answers to the series of questions below. When a `default answer' is available, it will follow the question in square brackets. For example, the question: What is your favorite color? [blue]: has the default answer 'blue'. Accept the default (without any extra typing!) by pressing thekey -- or type your answer and then press . Use the key to erase and aid correction of any mistyped answers -- before you press . Generally, once you press you move onto the next question. Once you've proceeded through all the questions, you will be given the option of modifying your choices before any files are updated. Hit ^C (Ctrl-C) at any time to quit without making changes. Pressto continue: (1) User Name Usernames consist of up to 16 alphanumeric characters, underscores and hyphens, but may not begin with a hyphen. Uppercase letters are discouraged in usernames.Username: test(2) Password Now, enter a password for this account. For security reasons you may want to use a password that is longer than 6 characters and that has at least one non alphabetic character. The password will *not* be echoed to the screen and you will be required to type it twice.Password: Retype new password:(3) User's Full Name Now, enter the full name for this account.Full Name: Test UserYou must specify a home directory. (4) Account Home Directory Where would you like to put the home directory for this account? Enter "1" for an account home directory: /home/test Or enter in any custom path (beginning with /).Select a number above or enter a path [1]:(5) Services Please select the services that this account will be using: ftp FTP services mail Email services shell shell login Enter the service name (e.g., "ftp", "mail", etc.) to toggle that service for the account. Hitwhen you are done selecting/deselecting services for this user. Select/deselect services [ftp mail]: ftp Select/deselect services [mail]:(6) Quotas Enter filesystem quotas for this user. The quota should be an integer (no decimal fractions) in megabytes (e.g., 5 = 5 megabytes). Enter 0 for no quota.Quota (MB): 0Account setup complete.
/etc/mail/virtusertable に以下に１行を追加しました。
info@*******.jp test
保存後、以下のコマンドを実行しました。
# makemap hash /etc/mail/virtusertable < /etc/mail/virtusertable
VirtualHost設定手順
squirrelmailはVirtualHostに対応していますので、Apache のVirtualHost設定を vaddhost コマンドで行いました。
以下は *******.jp ドメインの設定例です。
