Centos6.4 Configuring the Mail server postfix3.0.1 (a)

Mail server Deployment

1 Compiling and installing postfix

www.postfix.org

① because CentOS already has a postfix

[Email protected] ~]# Rpm-qa|grep postfixpostfix-2.6.6-2.2.el6_1.x86_64

So we have to uninstall it first

[Email protected] ~]# rpm-e postfix--nodeps

② get the source installation package from www.postfix.org

③ Unpacking Package

[Email protected] ~]# tar xf postfix-3.0.1.tar.gz [[email protected] ~]# CD postfix-3.0.1

④ Add user Postfix,postdrop before installation and enable dependent services to boot SASLAUTHD

[Email protected] ~]# groupadd-g 2525 postfix[[email protected] ~]# useradd-g 2525-u 2525-m-s/sbin/nologin postfix[ [Email protected] ~]# groupadd-g 2526 postdrop[[email protected] ~]# useradd-u 2526-g 2526-m-s/sbin/nologin postdrop

[[Email protected] ~]# service SASLAUTHD startstarting saslauthd: [OK][[email P Rotected] ~]# chkconfig SASLAUTHD on

⑤ Compiling and installing

[email protected] postfix-3.0.1]# make makefiles ' Ccargs=-dhas_mysql-i/usr/local/mysql/include-duse_sasl_auth-duse _cyrus_sasl-i/usr/include/sasl-duse_tls ' auxlibs=-l/usr/local/mysql/lib-lmysqlclient-lz-lrt-lm-l/usr/lib64/ Sasl2-lsasl2-lssl-lcrypto '

Attention:

1 if a/usr/bin/ld:cannot find-lmysqlclient error occurs, make sure that your MySQL path library specifies the correct

2 If error occurs while loading shared Libraries:libpcre.so.1:cannot open shared object File:error 40, make sure that/usr/local/lib has a pointer to L ibpcre.so.0.0.1 the link, and then be sure to Ldconfig, I got it for half an hour.

3 Please confirm each folder you can see the specific content, such as 64 to be modified to lib64

Eventually all interactions have default values to succeed

Postfix:warning:smtputf8_enable is true, but EAI support is not compiled in

Warning:you still need to edit myorigin/mydestination/mynetworks

Parameter Settings in/etc/postfix/main.cf.

See also http://www.postfix.org/STANDARD_CONFIGURATION_README.html

For information about dialup sites or about sites inside a firewalled

Network.

Btw:check your/etc/aliases file and is sure to set up aliases

That's send mail for root and postmaster to a real person, then run

/usr/bin/newaliases.

⑥ provides SYSV service script/etc/rc.d/init.d/postfix for Postfix:

Then give execute permission for this script:

[Email protected] postfix]# vim/etc/rc.d/init.d/postfix[[email protected] postfix]# chmod +x/etc/rc.d/init.d/postfix

Add the Postfix service to the list of services:

[[email protected] postfix-3.0.1] #chkconfig--add postfix

Set it to start automatically:

# chkconfig Postfix on

Test

[Email protected] postfix]# service postfix restart

Shutting down postfix: [OK]

starting postfix: [OK]

If the error postfix:warning:smtputf8_enable is true, but the EAI support was not compiled in, web-based EAI is multilingual, then set the smtpputf8_enable to No

[Email protected] postfix-3.0.1]# postconf "smtputf8_enable = no" [[email protected] postfix-3.0.1]# postfix start

[Email protected] postfix-3.0.1]# postfix startpostfix/postfix-script:starting the Postfix mail system

We found Port 25th on the monitor, OK.

Specifically, you can open the log file to view/var/log/maillog

And then

[[email protected] postfix]# newaliases start alias function

2 Configuring the Mail server

Control process: MASTER.CF

Master configuration file: main.cf

You can usually modify the configuration file with the postconf command

postconf-d Display the default settings

Postconf-n Display of modified content

POSTCONF-M Supported lookup Table model

POSTCONF-A display of supported SASL client plug-in types

POSTCONF-E parameter=value: Update values

SMTP Status code:

1XX: Pure Information

2XX: Correct

3XX: Operation not completed

4XX: Transient error

5XX: Permanent Error

SMTP protocol command:

Helo (SMTP)

EHLO (ESMTP)

Mail from: Description sender

RCPT TO: Specify recipients

Data

Alias: Mail Alias

/etc/aliases

By default, Postfix will relay to the local segment, as configured under Centos6.4 Configure Mail server postfix3.0.1 (ii)
