| How do I fix that and revert required permissions to the right place is sudo chown -R root:root / | |
| will help? right now none of my users can access their mailboxes. and I guess there is even more issues |
To fix permissions you could use Fix Permissions feature in Limits and Validation ⇾ Validate Virtual Servers page.

actually I still need help. Users got access to the webmin and usermin but I am unable to connect to the server neither from outside nor from localhost, I tried to check all config files and disable firewall and I cannot find the issue. I had a backup file on that machine so though I can recover but I see that even for this backup file this damn script changed user group and permissions to www-data:www-data. What can I do to restore access to the server from outside and inside and how to I roll back permissions etc now even if my backup file got corrupted?
Can you elaborate on this? It isn’t clear what’s going on!
sure. Users can login to usermin to their mailbox and send email. But when I am trying to connect over telnet I get Trying 213.199.48.111…
telnet: connect to address 213.199.48.111: Connection refused
telnet: Unable to connect to remote host
I have checked config file, ufw disabled. linux firewall has port 25 open. I don’t know where to look else 
New problem, new topic. Don’t change the subject.
the problem was the same with permissions, while recommendations from Illa helped to restore users access to usermin that didn’t help to restore access to the server.
I finally got it fixed by changing bunch of files permissions and reinstalling Postfix.
Here is what helped in case anyone has the same issue. I ran
ps aux | grep postfix
sudo postfix check
sudo postfix check returned

postfix/postfix-script: warning: not owned by postfix: /var/spool/postfix/active/7E0692521BFC
postfix/postfix-script: warning: not owned by postfix: /var/spool/postfix/trace
So I ran
sudo chown -R postfix:postfix /var/lib/postfix /var/spool/postfix/active /var/spool/postfix/trace
sudo systemctl restart postfix
Before that I checked all possible places.
Thanks guys! Hope this help someone else
