ドアホン画像を保存閲覧する設定(その1)

Last updated at Posted at 2021-05-24

Panasonicドアホンには、ドアホン子機・センサーカメラ・ワイヤレスカメラからの画像をメール送信する機能があり、このメールをRaspberryPiで受信する場合の設定をメモする。

背景

メールサーバの指定を smtp.gmail.com, smtp.mail.yahoo.co.jp, smtp.nifty.com など使って外部のメールに送信しても良いが、大量の画像メールの送信となると見通すことは困難だ。LAN内のローカルファイルに保存して、サムネール画像でブラウズ出来るようにした。

機材環境

・ドアホン親機 VL-MWH705(Panasonic)
・ドアホン子機 VL-VH556L x2
・センサーカメラ VL-CD265 x3
・ワイヤレスカメラ VL-WD813K
・RaspberryPi4 PiOSは /boot/issue.txt (2020-05-27) 版
　　ssh user@192.168.0.8 でログインしてroot操作できる環境とする

exim4 dovecot bind9 メールサーバ設定

○ パッケージのインストール
　apt-get install exim4 (exim4-base exim4-config)
　apt-get install dovecot-imap4 (dovecot-core)
　apt-get install bind9 (bind9-host bind9utils)

(1) /etc/exim4/update-exim4.conf.confの設定

egrep -v '^\s*#|^\s*$' /etc/exim4/update-exim4.conf.conf で内容を確認

dc_eximconfig_configtype='smarthost'
dc_other_hostnames='rapiq.localdom.jp'
dc_local_interfaces='127.0.0.1; 192.168.0.8; 192.168.1.28; ::1'
dc_readhost='rapiq.localdom.jp'  #メールを受け取るホスト名
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='smtp.nifty.com::587'  # gmail,yahoo でもOK
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname=''
dc_mailname_in_oh='true'
dc_localdelivery='maildir_home'   # IMAP4向け

(2) /etc/exim4/passwd.clientとpasswdの内容

外向きメール passwd.client　smarthost先の認証ユーザ名とパスワード。
受信用メール passwd　受信認証用のユーザ名とパスワード。

# cd /etc/exim4
# cat passwd.client
#smtp.gmail.com:user@gmail.com:pass
smtp.nifty.com:user@nifty.com:pass

# /usr/share/doc/exim4/examples/exim-adduser
User: user
Password: mypass
# cat passwd
user:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:mypass

(3) $HOMEにIMAP4用のディレクトリ作成

$ mkdir Maildir
$ chmod 700 Maildir

/usr/sbin/update-exim4.conf; /etc/init.d/exim4 restart で反映して再起動。

(4) dovecotの設定

# cd /etc/dovecot
# diff dovecot.conf.org dovecot.conf
24c24,25
< !include_try /usr/share/dovecot/protocols.d/*.protocol
---
> #!include_try /usr/share/dovecot/protocols.d/*.protocol
> protocols = imap
56a58,59
> auth_verbose = yes
> auth_debug = yes

# diff conf.d.org/10-mail.conf conf.d/10-mail.conf
30c30
< mail_location = mbox:~/mail:INBOX=/var/mail/%u
---
> mail_location = maildir:~/Maildir

# /etc/init.d/dovecot restart
[ ok ] Restarting dovecot (via systemctl): dovecot.service.

(5) bind9の設定

# cd /etc/bind
# diff -u named.conf.local.org named.conf.local
