I install an internal centos mail server with iredmail in the azure cloud, i can send emails from my user accounts
but the users doesnt receive the mails, first i have this error log message:

Jun 11 01:13:56 mail postfix/amavis/smtp[61016]: connect to 127.0.0.1[127.0.0.1]:10026: Connection refused

then i open the 10026 port for the amavis service but the amavis service cant be restarted and this is the message when i try:

Job for amavisd.service failed because the control process exited with error code.
See "systemctl status amavisd.service" and "journalctl -xe" for details.
