Webメールシステム - SquirrelMail
2013/01/28
 
SquirrelMail をインストールして、Yahoo メールや Hotmail のようなWebメールシステムを構築します。 ここの例ではメールサーバーにはローカルではなく、下記の通り、同一LAN内の別ホストのものを利用するように設定します。 よって、対象ホストにSMTP/IMAPサーバー導入済みが前提です。
 
www.srv.world
- SquirrelMail 導入サーバー

 
mail.srv.world
- SMTP/IMAPサーバー

When users click the Sign Out button they will be logged out and
then sent to signout_page. If signout_page is left empty,
(hit space and then return) they will be taken, as normal,
to the default and rather sparse SquirrelMail signout page.

Each IMAP server has its own quirks. As much as we tried to stick
to standards, it doesn't help much if the IMAP server doesn't follow
the same principles. We have made some work-arounds for some of
these servers. If you would like to use them, please select your
IMAP server. If you do not wish to use these work-arounds, you can
set this to "other", and none will be used.

This is the delimiter that your IMAP server uses to distinguish between
folders. For example, Cyrus uses '.' as the delimiter and a complete
folder would look like 'INBOX.Friends.Bob', while UW uses '/' and would
look like 'INBOX/Friends/Bob'. Normally this should be left at 'detect'
but if you are sure you know what delimiter your server uses, you can
specify it here.
To have it autodetect the delimiter, set it to 'detect'.

If you have already set the hostname and port number, I can try to
automatically detect the mechanisms your SMTP server supports.
Auto-detection is *optional* - you can safely say "n" here.
Try to detect auth mechanisms? [y/N]:
y
 
# yes (自動検出)

Trying to detect supported methods (SMTP)...
Testing none: SUPPORTED
Testing login: SUPPORTED
Testing CRAM-MD5: NOT SUPPORTED
Testing DIGEST-MD5: NOT SUPPORTED
What authentication mechanism do you want to use for SMTP connections?
none - Your SMTP server does not require authorization.
login - Plaintext. If you can do better, you probably should.
cram-md5 - Slightly better than plaintext.
digest-md5 - Privacy protection - better than cram-md5.
*** YOUR SMTP SERVER MUST SUPPORT THE MECHANISM YOU CHOOSE HERE ***
If you don't understand or are unsure, you probably want "none"
none, login, cram-md5, or digest-md5 [none]:
login
 
# login選択

SMTP authentication uses IMAP username and password by default.
Would you like to use other login and password for all SquirrelMail
SMTP connections? [y/N]:
n
