Hi, Henk. Please try the repair utility. There's likely a mail misconfiguration:

plesk repair mail -y

 

[H.W.B]

I did this :
Repairing the mail server configuration
Reconfiguring all domains and mailboxes ......................... [OK]

Error messages: 0; Warnings: 0; Errors resolved: 0

root@plesk:~#

 

[H.W.B]

I still receive this after the repair command :

Mar 9 10:46:46 plesk postfix/postmap[1839225]: fatal: open database >/dev/null.db: No such file or directory
Mar 9 10:46:47 plesk postfix/postmap[1839238]: fatal: open database >/dev/null.db: No such file or directory
Mar 9 10:47:49 plesk postfix/postmap[1839345]: fatal: open database >/dev/null.db: No such file or directory
Mar 9 10:47:50 plesk postfix/postmap[1839353]: fatal: open database >/dev/null.db: No such file or directory

Thank you for trying. In this case, I would suggest opening a ticket with Plesk support for further investigation directly on your server.

We are experiencing the same error.

Plesk Obsidian 18.0.77 Update 2
Web Host Edition
on Ubuntu 24.04.2 LTS

We could always recreate it by using Roundcube and attempting to send a newsletter-like mail (empty TO, around 70 BCC). We would immediately be greeted with the same log as above. The repair did not work around this problem.

Roundcube would just drop the attempt and connection after a while and display a connection error.

Our workaround was to setup the mail account in a mail program and send the draft mail there. This would ALSO lead to the same error messages as above, but the connection wouldn't drop - and after all the fatal errors, the mail would finally send to all recipients.

This is a new problem, our customers send mails like this regularly and it never failed before until now.
