安裝mysql以后需要做兩步處理.第一:設(shè)置環(huán)境變量的路徑 echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile ,;soure /etc/profile 第2步: echo "/usr/local/mysql/lib/mysql ">>/etc/ld.so.conf ; ldconfig? 這兩個(gè)步驟的目的是為了后面安裝courier-authlib做準(zhǔn)備,否則易出現(xiàn)"configure: error: --with-authmysql specified but no mysqlclient.so".設(shè)置mysql路徑的目的是courier-authlib執(zhí)行配置腳本時(shí)需要使用文件mysql-config. 如果沒有設(shè)置好這兩步,就是安裝好了courier-authlib,它的配置目錄里也不會(huì)有authmysqlrc文件! 安裝courier-authlib需要先安裝expect,用yum install expect比較省事. 檢查系統(tǒng),看是否存在文件courierauthconfig,一般在/usr/bin目錄。先mv courierauthconfig courierauthconfig.old,不然在編譯courier-authlib 會(huì)報(bào)“--with-mailgroup=vmail”之類的錯(cuò)誤。安裝好courier-authlib后需設(shè)定環(huán)境變量 COURIERAUTHCONFIG=/usr/local/authlib/bin/courierauthconfig [root@postfix ~]#? /usr/local/sbin/amavisd debug

BEGIN failed--compilation aborted at (. 81) line 2 這一類錯(cuò)誤產(chǎn)生的原因是缺少相應(yīng)的perl模塊,也是postfix安裝最麻煩的成分.它的處理方法是執(zhí)行 cpan? Crypt::OpenSSL::RSA 就可以很方便的安裝好這個(gè)模塊.再次執(zhí)行/usr/local/sbin/amavisd debug? 還會(huì)出現(xiàn)類似的問題,依照此法一一解決.記住這個(gè)慣例,在安裝時(shí)把斜線變成雙冒號(hào),同時(shí)省略文件的后綴(Crypt/OpenSSL/RSA.pm---->Crypt::OpenSSL::RSA.pm).實(shí)際上缺省的包大部分是2個(gè)斜杠的,如Archive/Zip.pm,做法也是相同的. 這是因?yàn)槿鄙倌KDBI.pm,執(zhí)行cpan DBI就解決了. postfixadmin配置文件config.inc.php需要特別注意的地方如下: // Mailboxes<?xml:namespace prefix = o />

// If you want to store the mailboxes per domain set this to 'YES'.

// Example: /usr/local/virtual/domain.tld/username@domain.tld

$CONF['domain_path'] = 'YES';

// If you don't want to have the domain in your mailbox set this to 'NO'.

// Example: /usr/local/virtual/domain.tld/username

$CONF['domain_in_mailbox'] = 'NO'; 默認(rèn)的值分別為"$CONF['domain_path'] ='NO'及$CONF['domain_path'] ='YES'.這樣修改后,在瀏覽器用postfixadmin添加郵件用戶時(shí),生成的目錄形式式為/var/mailbox/sery.com/sery.

Aug 17 11:30:43 postfix authdaemond: supplied password 'hzdgwy' does not match clearpasswd '$1$02d45893$je5tgY.9XFlJzOWiuiN.70'? 輸入的密碼本來是正確的,可是foxmail就是不能正確登陸收信,用web方式輸入用戶名和密碼,確實(shí)是正常的.什么原因?courier-authlib配置文件authmysqlrc加密的條目為"MYSQL_CLEAR_PWFIELD???? password",那么postfixadmin的配置文件config.ini.php相應(yīng)的項(xiàng)目應(yīng)為"$CONF['encrypt'] = 'cleartext';",默認(rèn)為"$CONF['encrypt'] = 'md5crypt';",改成一致后就能驗(yàn)證了.另外webmail(extmail)的文件webmail.cf的條目也得是"SYS_CRYPT_TYPE = cleartext". ? cleartext把密碼也明文方式存儲(chǔ)在數(shù)據(jù)庫中 ? ? 使用pop3 over ssl 一共4步（假定安裝目錄為/usr/local/imap） 1、進(jìn)入目錄 /usr/local/imap/share 修改一下文件mkpop3dcert，這個(gè)把有效期改一下，其結(jié)果如下（默認(rèn)一年--365天，紅色字體為更改值）

2、執(zhí)行命令 /usr/local/imap/share/mkpop3dcert ，在同一目錄生成所需的文件pop3d.pem ? 3、啟動(dòng)pop3-ssl。執(zhí)行命令 /usr/local/imap/libexec/pop3d-ssl.rc start? 就ok。 執(zhí)行后用netstat -anp|grep 995 檢查一下是否監(jiān)聽。 tcp??????? 0????? 0 :::995????????????????????? :::*??????????????????????? LISTEN????? 2412/couriertcpd 4、客戶端更改。把客戶端的pop端口由110改成995。然后收取一下，這樣就能準(zhǔn)確無誤的驗(yàn)證ssl功能是否正常。
