This is a quick post that lists commands to start, stop postfix service.
Postfix is a free and open-source mailing service. It was developed by IBM and is a common alternative to Sendmail service.
How to start, stop and reload postfix mail service
You can use
postfix command directly or you can use OS service management commands.
[root@kerneltalks ~]# postfix start postfix/postfix-script: starting the Postfix mail system [root@kerneltalks ~]# postfix stop postfix/postfix-script: stopping the Postfix mail system [root@kerneltalks ~]# postfix reload
service command to control postfix service.
[root@kerneltalks ~]# service postfix start Redirecting to /bin/systemctl start postfix.service [root@kerneltalks ~]# service postfix stop Redirecting to /bin/systemctl stop postfix.service [root@kerneltalks ~]# systemctl start postfix [root@kerneltalks ~]# systemctl stop postfix
IPv6 error in postfix
Sometimes you see below error while dealing with postfix service.
[root@kerneltalks ~]# postfix start postfix: fatal: parameter inet_interfaces: no local interface found for ::1
This is due to your system is using IPv6 as well along with IPv4. If you don’t need IPv6 then you can safely disable IPv6 and then restart postfix service to resolve the above error.
Another way is to disable postfix IPv6 support and get rid of this error. To do that you need to edit
/etc/postfix/main.cf configuration file and change inet_protocols to ipv4.
[root@kerneltalks ~]# vi /etc/postfix/main.cf #inet_protocols = all inet_protocols = ipv4
Save changes and restart
