sieve

sieve は cyrus-imapd で利用出来るメールの振分系です。

cd mail/cyrus-imapd make package

で設置されます。sieve での振分を設定する言語は RFC 3028 で定義されています。例えば次のようなところに情報があります。

S.C. MAGI-SYSTEM 日記から: http://www.magisystem.net/diary/?20040321
RFC 3028 (英語): http://rfc.sunsite.dk/rfc/rfc3028.html
Cyrus IMAP serverでsieveを使う: http://www.j.dendai.ac.jp/~fujimoto/FreeBSD/cyrus-sieve.html

設定

/usr/pkg/etc/cyrus.conf /usr/pkg/etc/imapd.conf

serv timsieved[18469]: can't use home directories

sieveusehomedir: true
 |
 v
## sieveusehomedir: true

.sieve

allof とか anyof を見ると、いささか「何だらう」と思ふが、これは単に AND や OR の意味をさふ書くだけらしい。

記述	意味
anyof	OR
allof	AND

.sieve を生成するための元の譜には次のような形の文を書きます。

 if anyof (not exists ["From", "Date"],
                   header :contains "from" "fool@example.edu") {
                discard;
             }

つまり、次のような形式です。

if ( 論理 ) { 操作 }

あるいは:

if ( 論理 ) { 操作 }
else (    ) {   }

上記例	意味
if	control commands
論理	test commands
操作	action commands

暗黙に保存 implicit keep : 何も指定がない場合には、単に保存する

操作

action commands に書けるのは次のやうなものです。

操作	意味
reject	受取らない
fileinto	譜に保存
redirect	転送
keep	通常の処理 (メール box に保存)
discard	捨てる

検査

test commands には次のものが書けます。

検査	意味	例
address
allof	AND
anyof	OR
envelope	メール転送情報(発信元等)
exists
false
header	メールの見出に	header :is "Sender"....
not
size
true

missing package:

cy2-login-2.1.22    Cyrus SASL LOGIN authentication plugin
cy2-plain-2.1.22    Cyrus SASL PLAIN authentication plugin

Following one was installed at above testing, but it is said confusing. Without this package, it is OK now.

cy2-crammd5-2.1.22  Cyrus SASL CRAM-MD5 authentication plugin
