Transport returned 67


I have a strange error on a newly deployed server.
When I try to send a mail to a mailbox on the server I’ve got this error :

2024-01-29 15:34:41 1rUSib-000LIM-1h ** [email protected] R=localuser T=dovecot_virtual_delivery: Child process of dovecot_virtual_delivery transport returned 67 (could mean user nonexistent) from command: /usr/lib/dovecot/dovecot-lda

The user exist… I can connect with the webmail without problem, I can send mail without problem…

Any idea on what can cause that issue ?

ok, I have found the problem, the account was not created in the account file in home mail conf… I have probably do something wrong at some point…
