postfix本地郵件投遞的過程？

boyhyc

在配置好一個(gè)postfix郵件服務(wù)器后，對(duì)postfix本地郵件投遞過程不是很明白，那位能給哪位能不能給講解一下；
   我現(xiàn)在的郵件server也還有些問題，我配置的是
postfix+mysql+courier-authlib+courier-imap
通過虛擬域和虛擬用戶來收發(fā)郵件，現(xiàn)在對(duì)外發(fā)送郵件沒有問題，但是本地虛擬用戶發(fā)送有問題，發(fā)送給本地虛擬用戶的郵件，在投遞時(shí)好像都在系統(tǒng)用戶里去確認(rèn)去了，如果系統(tǒng)用戶（/etc/passwd）里沒有則就投遞失�。�
下面是發(fā)送時(shí)的日志信息

Jul 26 11:54:07 testmail authdaemond: received auth request, service=smtp, authtype=login
Jul 26 11:54:07 testmail authdaemond: authmysql: trying this module
Jul 26 11:54:07 testmail authdaemond: SQL query: SELECT username, password, "", '89', '89', homedir, maildir, "", uid, "" FROM mailbox WHERE username = "huang@testhuang.com"
Jul 26 11:54:07 testmail authdaemond: password matches successfully
Jul 26 11:54:07 testmail authdaemond: authmysql: sysusername=<null>, sysuserid=89, sysgroupid=89, homedir=/home/mail, address=huang@testhuang.com, fullname=huang, maildir=testhuang.com/huang/Maildir/, quota=<null>, options=<null>

Jul 26 11:54:08 testmail postfix/smtpd[10095]: lost connection after RCPT from unknown[192.168.0.16]

如果系統(tǒng)用戶存在了，則郵件就投遞到了用戶相應(yīng)的主目錄下/home/test,我設(shè)置的虛擬用戶的maildir在/home/mail/下，正常投遞應(yīng)該要投遞到/home/mail/testhuang.com/huang/Maildir/new下去阿；可以確定的是接收時(shí)都是在/home/mail/testhuang.com/huang/Maildir/new這個(gè)目錄下接收的，我試過將投遞到/home/test/Maildir/new下的郵件拷貝到/home/mail/testhuang.com/huang/Maildir/new后可以接收走（outlook和extmail試驗(yàn)）
所以說問題就是投遞的時(shí)候?yàn)槭裁磿?huì)由系統(tǒng)用戶來判斷呢？ 這個(gè)與mail.cf設(shè)置有關(guān)系嗎？為什么發(fā)給本地虛擬用戶的郵件不去mysql里確認(rèn)呢？
我在里面添加上local_transport=virtual后還是一樣的問題……
請(qǐng)各位有經(jīng)驗(yàn)的同仁指教一下
謝了

SQL query: SELECT username, password, "", '89', '89', homedir, maildir, "", uid, "" FROM mailbox WHERE username = "huang@testhuang.com"
你看一下你的authmysqlrc文件的詳細(xì)配置。

boyhyc

MYSQL_SERVER            localhost
MYSQL_USERNAME          extmail
MYSQL_PASSWORD          extmail

MYSQL_PORT              3306
MYSQL_OPT               0
MYSQL_DATABASE          extmail

MYSQL_USER_TABLE        mailbox
MYSQL_CRYPT_PWFIELD     password
MYSQL_UID_FIELD         '89'
MYSQL_GID_FIELD         '89'
MYSQL_LOGIN_FIELD       username
MYSQL_HOME_FIELD        homedir

MYSQL_NAME_FIELD        uid
MYSQL_MAILDIR_FIELD     maildir

能是這個(gè)設(shè)置的問題嗎？日志里不都顯示password matches successfully么？
我的感覺就是在投遞的時(shí)候并沒有去mysql里確認(rèn)，因?yàn)槿绻�只要存在相�?yīng)的系統(tǒng)用戶，郵件就可以投遞出去了。也就是本地投遞時(shí)他到/etc/passwd里確認(rèn)有無這個(gè)用戶.奇怪……

把 mydestination = $myhostname, $mydomain
改成
mydestination = $myhostname
mydestination 里的表示本地域

好像不是這里的問題，改了還是不行

正常的情況下，如果收件域名在virtual_mailbox_domains里，并且
virtual_transport = virtual
那么應(yīng)該是用系統(tǒng)的virtual進(jìn)行投遞，投遞的時(shí)候要查詢virtual_mailbox_maps 來確定用戶名對(duì)應(yīng)的投遞目錄
之前的esmtp認(rèn)證和投遞是兩回事

可以通過下面的命令確定一下某地址到底投遞到哪個(gè)目錄去了

postmap -q huang@testhuang.com mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

正常的應(yīng)該顯示 testhuang.com/huang/Maildir 類似的東西

boyhyc

先謝過樓上的朋友
但是現(xiàn)在我現(xiàn)在的狀態(tài)還是比較奇怪，不知道是哪個(gè)地方的設(shè)置出了問題
郵件投遞的時(shí)候好象并沒有到virtual_mailbox_maps去確定目錄，而是根據(jù)/etc/passwd來確定用戶，所以郵件也自然就投遞到了用戶的家目錄下。
好象就是在投遞的過程中虛擬用戶和域都沒生效了，哪位高人能不能講解一下postfix的具體投遞過程呢？為什么在認(rèn)證的時(shí)候都是通過虛擬域來實(shí)現(xiàn)了，而在投遞的時(shí)候卻不能呢！
郁悶
這樣的問題好象都沒人遇到過……

boyhyc

經(jīng)過樓上朋友和extmail老大的指點(diǎn)又明白了些
將mydestination里去掉$mydomain后，郵件可以投遞到服務(wù)器上去了，但是還是一直在隊(duì)列里沒有發(fā)送成功，在日志里面顯示

并一會(huì)后就有如下的警告信息：

Jul 27 08:01:32 testmail postfix/master[9559]: warning: /usr/libexec/postfix/virtual: bad command startup -- throttling

上面這個(gè)之前我也好像也遇到過，好像就是郵件一直試著去投但是就是沒成功，顯示未提供目錄類型？
是指maildir的類型嗎？還有下面兩條就不太明白了。
那位朋友還能給解答一下……

Aryang

fatal: unsupported dictionary type: postfix
估計(jì)你哪的配置寫錯(cuò)了，
在 virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf 這個(gè)里，mysql就是所謂的dictionary type，你是不是在某些地方寫了 xxx_maps = postfix:/xxxxxxxxxxxxxxxxx
用
postconf | grep postfix:
看看是不是有這樣的配置
