Mailformed configuration of /etc/postfix/main.cf
After upgrading to ISPConfig 3.2.5 it seems the main.cf of postfix is malformed. Two servers I upgraded had the same issue and were not able to send mails aufter the upgrade (mail queue showed an "unknown mail transport error").
Looking into /etc/postfix/main showed a missing linebreak between
smtp_bind_address = <IP>smtpd_reject_unlisted_sender = no
After changing this to
smtp_bind_address = <IP>
smtpd_reject_unlisted_sender = no
Steps to reproduce
I can't reproduce the error as all my servers are upgraded at the moment. But here are the steps I did on two ISPConfig installations
- started the update of ISPConfig
- Reconfigured all service whith the update wizard
- tried to send mails on the maschine
The mails should have been sent.
Server OS + version: Ubuntu 20.04
