Now try to send a test email using the command below:įOR Centos: echo "This is the body of the email"| mail -r"Sender-Display-Name" -s "This is the subject(E-Mail from SMTP Relay) line" FreePBX under Voicemail admin you must change the senders address to match your account as well as the sender for notifications such as backups etc. Now restart Postfix ~]# systemctl restart postfix Next let’s correct the file ~]# chown root:root ~]# chmod 0600 ~]# postmap /etc/postfix/generic replacing localhost.localdomain and with your service hostname and the email user are using Go the end of file and append following lines. Next, we need to configure generic file in order to be able to send emails as a valid user (this is required for ~]# vi /etc/postfix/generic Now change permission for this ~]# chown root:postfix ~]# chmod 640 /etc/postfix/sasl_passwd Next we need to edit the configuration for the postfix SASL ~]# vi /etc/postfix/sasl_passwdĪdd a line below :587 with your sender account detailsĪ Postfix lookup table must now be generated from the sasl_passwd text file by running the following ~]# postmap /etc/postfix/sasl_passwd ![]() # smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt Smtp_generic_maps = hash:/etc/postfix/generic Smtp_sasl_tls_security_options = noanonymous Smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd Postfix’s main configuration file is main.cf and that is where we make the required change as ~]# vi /etc/postfix/main.cfĪppend the following lines masquerade_domains = domainname FreePBX uses centos 7 and postfix fom its mail delivery, normally this is fine unless the customer is using Office 365 mail then there can be delivery issues.įirstly you will need to set up a user in Office 365 for the system. ![]()
