Postfix is now set up with a default configuration. If you need to make

まずは、バーチャルドメイン管理ユーザー(10000:10000)の"post"を追加。
$ sudo groupadd -g 10000 post
$ sudo useradd -u 10000 -g 10000 -d /home/post -s /sbin/nologin post
$ sudo mkdir /home/post
続いて、/etc/postfix/main.cfを編集。
## Virtual Domain support
virtual_mailbox_base = /home/post
virtual_alias_maps = hash:/etc/postfix/virtual
virtual_alias_domains = $virtual_alias_maps
virtual_mailbox_domains = $mydomain
virtual_mailbox_maps = hash:/etc/postfix/vmailbox
virtual_minimum_uid = 10000
virtual_uid_maps = static:10000
virtual_gid_maps = static:10000
virtual_mailbox_limit = 512000000
そして/etc/postfix/vmailboxにメールアカウントを設定。実際はbravotouring.comは自宅で使用中なので、ここではテスト用のドメインとしておく。
# bravotouring.com設定終了後、
yano@test.com yano/Maildir/
mail@test.com mail/Maildir/
yoko@test.com yoko/Maildir/
natsumi@test.com natsumi/Maildir/
$ sudo postmap /etc/postfix/vmailboxを忘れずに。
さらに/etc/postfix/virtualに転送用エイリアスを設定。
# bravotouring.comこちらも
webmaster@test.com yano@test.com
postmaster@test.com yano@test.com
domainadmin@test.com yano@test.com
$ sudo postmap /etc/postfix/virtualを忘れずに。
ここまでやって、/var/log/mail.logで外部からyano@test.com宛のメール受信を確認OK。
続いてpop対応すべく、/usr/local/etc/dovecot-passwdにpopアカウントを設定。
yano:{plain}PASSWORD言うまでもなく"PASSWORD"は実際のパスワードになるのだが、{plain}に続けてプレーンテキストで書けばよい。こちらは後処理不要。
mail:{plain}PASSWORD
yoko:{plain}PASSWORD
natsumi:{plain}PASSWORD
あとは/etc/dovecot/auth.d/01-dovecot-postfix.authを書いてサクっと受信OKとなるはずだったのが、さにあらず。
mechanisms = plain loginと書いたのに
socket listen {
client {
path = /var/spool/postfix/private/dovecot-auth
mode = 0660
user = postfix
group = postfix
}
}
passdb passwd-file {
args = /usr/local/etc/dovecot-passwd
}
userdb static {
args = uid=10000 gid=10000 home=/home/post/%n/Maildir
}
dovecot: POP3(yano): stat(/home/post/yano/Maildir/tmp) failed: Permission denied (euid=1000(yano) egid=1000(owner) missing +x perm: /home/post/yano)というエラーに悩まされ続けた。
2日間に渡る悪戦苦闘の結果、/etc/dovecot/dovecot.confに残るuserdbブロック
userdb passwd {と競合している気がしたので、こちらをコメントアウトしてようやくPOP受信まで成功。
# [blocking=yes] - By default the lookups are done in the main dovecot-auth
# process. This setting causes the lookups to be done in auth worker
# proceses. Useful with remote NSS lookups that may block.
# NOTE: Be sure to use this setting with nss_ldap or users might get
# logged in as each others!
#args =
}
明日はSMTP送信だ。
