Issue New mails not being properly created

[NeoTrafy]

Server operating system version

Almalinux 9.5

Plesk version and microupdate number

18.0.66 #2

I migrated to a new server and wanted to move the mailnames folder to a new location editing main.cf
Default: /var/qmail/mailnames
Moved to: /data/mailnames

The thing is after a few weeks mail stoped working. Mail said had no permissions to create folders or something like that and the main.cf reset to the default folder so I copied the mailnames to the default path and everything started to work again.
But today I noticed that even everyone was working without problems, the new subscriptions I create they use the /data/mailnames folder instead of the default path.

I had an announcement in the plesk gui saying I had to do plesk mail repair and after that the virtual_mailbox_base changed again to /data/mailnames instead of the default.

I already checked in the FAQ and it says the customized entries are reverted automatically after an update or if you do the plesk repair. Where can I change that so the default remains instead of changing again to the path I edited 6 weeks ago. And how's that possible that if the mailbox_base is routed to /var/qmail/mailnames the new subscriptions use the /data/mailnames? I cannot create mails for those subscriptions because they're being generated wrong.

Greetings.

Hello, @NeoTrafy Have you changed anything else apart from the virtual_mailbox_base value in the /etc/postfix/main.cf file or in another configuration file? Could you confirm what's the value of mydestination and the exact error message you encounter, if any?

Hello,
In main.cf I have the

virtual_mailbox_base = /var/qmail/mailnames
mydestination = localhost.$mydomain, localhost, localhost.localdomain

But when the new mails of new subscriptions are created they show up in /data/mailnames instead of the /var/qmail/mailnames.
Another strange thing is when a mail is received this is what's logged:

Jan 17 09:56:55 sv03 postfix-local[761579]: 5977EC000FE4: from=<external@domain>, to=<[email protected]>, dirname=/datos/mailnames but anyway the mail delivered to the /var/qmail/mailnames

I'm doing some tests and it seems like at the moment of creating the mail account it's created in the /datos/mailnames and once he tries to save the first mail or login it run the mkdir in the /var/qmail/mailnames but as the domain folder is not already available (or it's being created as popuseropuser which has no permission as the mailnames folder is root:root) it fails:
Jan 17 03:58:29 sv03 dovecot[365960]: service=lda, user=[email protected], ip=[]. Error: mkdir(/var/qmail/mailnames/newclient.com/hi/Maildir) failed: Permission denied (euid=30(popuser) egid=30(popuser) missing +w perm: /var/qmail/mailnames, dir owned by 0:0 mode=0755)

If I manualy cp -avr /datos/newclient.com to /var/qmail/mailnames after that it works as expected, but it's a bit insane that he's using the wrong path or even change the default /var/qmail/mailnames path to /datos/mailnames after updates or plesk repair.

Thanks for your time.

Thank you for the confirmation. Could you please also confirm what does the following command returns:

grep PLESK_MAILNAMES_D /etc/psa/psa.conf

if the correct folder is returned, I would suggest opening a ticket with our support team, so they can log into the server and further troubleshoot what is causing the behavior with new subscriptions.
