Centos 6.5 configuration postfix and troubleshooting

1. Domain settings:

2. Change the name of the server:

3. Install it in the following ways:

yum-y install postfix

/etc/init.d/postfix start

Chkconfig Postfix on

Netstat-tunlp

Ps-ef |grep Postfix

To modify the master configuration file:

Vi/etc/postfix/main.cf

The first one is to modify Myhostname = postfix.com is to modify our mail domain to postfix.com

The second inet_interfaces = All is to modify the listening interface for all

Then we use POSTCONF-N to check the main parameters of the modified configuration file.

4. Installing Dovecot

Yum-y Install Dovecot dovecot-devel dovecot-mysql pam-devel

Dovecot–-version

/etc/init.d/dovecot start

Chkconfig Dovecot on

/etc/init.d/portreserve stop

Chkconfig Portreserve off

Let's configure the Dovecot service.

Vim/etc/dovecot/dovecot.conf

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/8B/66/wKioL1hNWC_BZcE9AAAX2k1hwwY362.png "title=" 2.png " alt= "Wkiol1hnwc_bzce9aaax2k1hwwy362.png"/>

Then restart the postfix and Dovecot services

The error it shows is that the solution to the permissions problem is to give /var/mail/$USER 777 Permissions

Chmod-r 777/var/mail

Error 3:

The error message that it displays is that the mail user's mail directory is not set to modify the following files

Error 4: can not send, the following error occurred

Workaround:

The first is: Modify the postfix configuration file main.cf in the Mynetworks, modified as follows all the network segments are passed on it.

Mynetworks = 0.0.0.0/0

This approach has security implications.

The second is: Modify the postfix configuration file main.cf, let

$mynetworks = 127.0.0.0/8, 127.0.0.1

And then add

Smtpd_client_restrictions = Permit_mynetworks, permit_sasl_authenticated,
