postfix安装记录五-安装过程的出现的问题

配置过程中出现的一些问题:

1,如果日志中出现如下提示

Oct5 15:07:03 mail postfix/smtpd[3522]: connect frommail.test.com[192.168.80.58]
Oct 5 15:07:30 mail authdaemond: received authrequest, service=smtp, authtype=login
Oct5 15:07:30 mail authdaemond: authmysql: trying this module
Oct5 15:07:30 mail postfix/smtpd[3522]: warning: SASL authenticationfailure: could not verify password
Oct 5 15:07:30 mail postfix/smtpd[3522]: warning:mail.test.com[192.168.80.58]: SASL login authentication failed: generic failure
Oct5 15:07:30 mail authdaemond: failed to connect to mysql server(server=localhost, userid=extmail): Can't connect to local MySQL server through
socket '/tmp/mysql.sock ' (2)
Oct5 15:07:30 mail authdaemond: authmysql: TEMPFAIL - no more modules willbe tried

解决思路：除了要坚持smtpd.conf和authdaemon的权限之外还需要彻底的检查authmydqlrc这个配置文件，尽量不要去复制网上的文件，手工配置.

[root@mail authlib]# perl -MMIME::Base64 -e"print encode_base64('test1@test.com');"
dGVzdDFAdGVzdC5jb20=
[root@mail authlib]#
[root@mail authlib]# perl -MMIME::Base64 -e"print encode_base64('123456');"

2、日志中出现许多类似的日志提示：

Oct6 18:13:56 mail imapd: Maximum connection limit reached for192.168.40.218
而且客户端出现下面的提示，





解决如下
[root@mail ~]# perl -p -i -e's/^MAXDAEMONS=40/MAXDAEMONS=80/g'
/usr/local/courier-imap/etc/imapd
[root@mail ~]# perl -p -i -e's/^MAXPERIP=4/MAXPERIP=40/g' /usr/local/courier-imap/etc/imapd

/etc/init.d/courier-imap stop
/etc/init.d/courier-imap start

3、如果报错提示：

DBD::mysql::st execute failed: DELETEcommand denied to user 'extmail'@'localhost' for table 'domain_manager' at
/var/www/extsuite/extman/libs/Ext/Mgr/MySQL.pmline 757.

解决：进入mysql
grant all privileges on *.* to'extmail'@'localhost' identified by 'extmail' with grant option;
Query OK, 0 rows affected (0.00 sec)

4、验证不通过问题
[root@mail extra]# perl -e 'useMIME::Base64; print
encode_base64("postmaster\@extmail.org")';
cG9zdG1hc3RlckBleHRtYWlsLm9yZw==
[root@mail extra]# perl -e 'useMIME::Base64; print encode_base64("extmail")';

5355.7.8 Error: authentication failed: generic failure

解决
1、查看/usr/local/sasl2/lib/sasl2/smtpd.conf的权限
-rw-r--r-- 1 root root148 Oct1 21:14 smtpd.conf

修改为
-rwxr-xr-x 1 root root148 Oct1 21:14 smtpd.conf

2、查看/usr/local/courier-authlib/authdaemon 权限
drwxr-x--- 2 vmail vmail 4096 Oct3 00:53 authdaemon

修改为
[root@mail spool]# chmod 755 authdaemon/
drwxr-xr-x 2 vmail vmail 4096 Oct3 00:53 authdaemon

[root@mail spool]# cd authdaemon/
[root@mail authdaemon]# ll
total 4
-rw-r--r-- 1 root root 5 Oct3 00:53 pid
-rw------- 1 root root 0Oct1 20:54 pid.lock修改为下面的权限
srwxrwxrwx 1 root root 0 Oct3 00:53 socket
[root@mail authdaemon]# chmod 755 pid.lock
[root@mail authdaemon]# ll
total 4
-rw-r--r-- 1 root root 5 Oct3 00:53 pid
-rwxr-xr-x 1 root root 0 Oct120:54 pid.lock
srwxrwxrwx 1 root root 0 Oct3 00:53 socket

5、如果邮件服务器搭建完毕后只收不到邮件，有可能是你装了反垃圾邮件后，在测试邮件时垃圾邮件被过滤掉了，因为默认的
# $final_spam_destiny = D_BOUNCE; //不传递给收件人

修改为

$final_spam_destiny = D_PASS; //不做任何处理，直接传送给收件人

6、没有加载mysql连接出现的问题
configuration files.
config_directory: [] /etc/postfix
bin/postconf: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
bin/postconf: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
bin/postconf: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory

Please specify the final destination directory for installed Postfix
administrative commands. This directory should be in the command search
path of adminstrative users.

解决方法如下

# vi /etc/ld.so.conf
/usr/local/mysql/lib
# ldconfig

7、卸载sasl软件
--nodeps来卸载，出现error: specifies multiple packages错误，于是再加一个--allmatches这下可以成功卸载了。
[root@localhost]# rpm -qa | grep cyrus-sasl | xargs rpm -e --nodeps
　　error: "cyrus-sasl-lib-2.1.22-5.el5_4.3" specifies multiple packages
　　error: "cyrus-sasl-lib-2.1.22-5.el5_4.3" specifies multiple packages
　　error: "cyrus-sasl-plain-2.1.22-5.el5_4.3" specifies multiple packages
　　error: "cyrus-sasl-plain-2.1.22-5.el5_4.3" specifies multiple packages
　　[root@localhost courier-imap-4.1.0]# rpm -qa | grep cyrus-sasl | xargs rpm -e -nodeps
　　-nodeps: unknown option
[root@localhost]# rpm -qa | grep cyrus-sasl | xargs rpm -e --allmatches
　　error: Failed dependencies:

[root@localhost]# rpm -qa | grep cyrus-sasl | xargs rpm -e --allmatches --nodeps

8、在初安装时maillog里面会有如下的提示：
Prototype mismatch: sub Encode::IMAPUTF7::decode ($$;$) vs none at /opt/www/extman/libs/Encode/IMAPUTF7.pm line 76.
Prototype mismatch: sub Encode::IMAPUTF7::decode ($$;$) vs none at /opt/www/extman/libs/Encode/76

在网上根据ttp://www.siutung.org/post/508/ 这个网友写的 采用第一种方法解决
解决：
（1)、下载并解压
# axel -a http://search.cpan.org/CPAN/authors/id/P/PM/PMAKHOLM/Encode-IMAPUTF7-1.05.tar.gz （官方当前最新版本）
# tar -zxvf Encode-IMAPUTF7-1.05.tar.gz
2、编译并复制到目标目录覆盖源文件（建议覆盖前将源文件备份）
# cd Encode-IMAPUTF7-1.05
# perl Makefile.PL
# cd lib/Encode
# cp IMAPUTF7.pm extman/libs/Encode/ （此处请根据实际输入正确的extman路径）1
另：

(2)、extmail官方解决方法：
编辑Encode-IMAPUTF7.pm文件（修改之前注意备份）
将“no warnings 'redefine';^M”那一行修改成“no warnings;”或“no warnings qw(prototype redefine);”

9、在启动postfix时日志里可能会出现以下问题：

Mar 29 06:04:06 bogon postfix/bounce[22442]: fatal: open /etc/postfix/bounce.cf: No such file or directory

解决方法：
cd /etc/postfix/
cp -p bounce.cf.default bounce.cf
