Second domain trouble - firs domain work correctly

kopevi · May 14, 2026, 9:10am

I have trouble with addition of second domain. Everything looks good, but when I go to webmail there is problem with outgoing messages - it is not able to save outgoing email into folder, and roundcube send me this alert:

“Chyba serveru: STATUS: Internal error occurred. Refer to server log for more information. [2026-05-12 19:47:26] (0.002 + 0.000 + 0.001 secs).” Chyba serveru means - sever fail.

And here is list of directories of second mail:

     400 atmex.group/atmadm/dovecot.list.index.log
      35 atmex.group/atmadm/maildirsize

I thing here is problem with acces to new directory, because directories of first mail are correct.

I would like to ask how i can solve this problem?

Thank you for any help.

How did you add the domain? Is atmadm a user or an alias?
What are the ownership rights of the mail folder?

kopevi · May 14, 2026, 2:16pm

Hello,
I manualy add admin user account atmadm(at)atmex(dot)group via box.example(dot)net/admin
In the first:
I add dns records to ns1.box.example(dot)net and ns2.box.example(dot)net in ISP admin section of atmex.group domain
2.) i wait about one hour and then i add new admin user for atmex.group : atmadm@atmex(dot)group , in box.example(dot)net/admin

3.) i try to send an emai to my gmail account, it is working but my emails of atmadm@atmex(dot)group are not able to store in a directory on the server

Here is output of mailboxes directory

$  ls -la
total 0
drwxrwxr-x 1 mail mail 0 May 12 22:33 atmex(dot)group
drwxrwxr-x 1 mail mail 0 May 12 22:33 ludacka(dot)net

I have an update:
If i try to add a new user for primary domain, there is the problem like for second domain… I updated VPS last week and there was update for PHP, before that it worked correctly.

KiekerJan · May 15, 2026, 8:49pm

I’m not certain that the php issue impacts this bit of Roundcube. I can’t yet reproduce it. Also, Roundcube uses IMAP to store messages so that should also not be impacted.

Can you check sudo journalctl -u mailinabox? Maybe there’s a message there around the time you created the new users.

kopevi · May 15, 2026, 9:04pm

I try to add new user: without respond to fail in journalctl -u mailinabox

----on the webmail same situation

and output from journalctl -u mailinabox

Not familiar with these errors, but some googling points at filesystem or apparmor issues. Which VPS provider are you using? Is there a special filesystem where /home/ is stored?

I use czech vps provider vpsfree.cz , there is NixOS with Ubuntu 22.04. virtual machine. I think the problem is in the path (/home/user-data//mail/.....
there is two //, but i dont know why and I dont know how it solve - It could be in some script.

Error: Couldn't create mailbox list lock /home/user-data//mail/mailboxes/atmex.group/test2/mailboxes.lock: file_create_locked(/home/user-data//mail/mailboxes/atmex.group/test2/mailboxes.lock) failed: link(/home/user-data//mail/mailboxes/atmex.group/test2/mailboxes.lockc2ea457d15dbf665, /home/user-data//mail/mailboxes/atmex.group/test2/mailboxes.lock) failed: Operation not permitted

Do you know how to perform a clean install while retaining the correct (previously used) DNSsec records? My registrator entered these records manually (and given the email correspondence with them, it will take a while).
Thank you.
