  • Support for BIND DNS has been removed from Plesk for Windows due to security and maintenance risks.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS.

Resolved plesk sendmail does not work

Suddenly I receive new error messages in var/log/mail.err

h2828820 postfix/sendmail[7558]: fatal: open /etc/postfix/main.cf: Permission denied
Feb 1 21:13:00 h2821220 plesk-sendmail[7557]: S7546: sendmail unsuccessfully finished with exitcode 75
Feb 1 21:13:00 h2821220 postfix-local[7546]: D3B5E140076: Unable to send message. sendmail status: 75
Feb 1 21:13:00 h2821220 postfix-local[7546]: D3B5E140076: Unable to send mail for: <internal E-Mail address>

The internal forwarding of E-Mails does not work and sending of Plesk-messages does also not work.
Any idea?
 
More likely a permission issue. Please run the following command via SSH

Bash:
chmod 755 /etc/postfix

See if that works.
 
Was the problem! Looking for a solution last night I found a 2nd issue. After server restart and #postfix check there were a differenc between

1. etc/resolv.conf =>
...
nameserver 127.0.0.1
nameserver 127.0.0.53

and
2. /var/spool/postfix/etc/resolv.conf
...
nameserver 127.0.0.1nameserver 127.0.0.53

I also fixed 2.

Not sure whether these both issues belongs together.

However, now forwarding works again. Thank you!
