Hello everyone,
I have following configurations (and more) at /etc/dovecot/local.conf in
a "/VirtualUserFlatFilesPostfix/" setup :
[partial file content begins]
protocols = imap pop3 lmtp sieve
mail_location = maildir:~/data:INBOX=~/data/.INBOX
service lmtp {
unix_listener /var/spool/postfix/private/dovecot-lmtp {
user = vmail
group = vmail
mode = 0660
}
}
protocol lmtp {
postmaster_address = postmas...@example.net
mail_plugins = $mail_plugins sieve
}
userdb {
driver = passwd-file
args = username_format=%u /srv/vmail/domains.d/%d/users.d/%n/etc/passwd
}
passdb {
driver = passwd-file
args = username_format=%u
/srv/vmail/domains.d/%d/users.d/%n/etc/shadow.%Ls
}
service auth {
unix_listener /var/spool/postfix/private/auth {
user = postfix
group = postfix
mode = 0660
}
}
[/partial file content ends]
Everyting works (IMAP mail is stored, IMAP/POP3 mail is retrieved,
incoming SMTP mail from Postfix is delivered, Outgoing SMTP senders are
authenticated from Postfix~SASL) BUT:
When incoming mail goes to a mailbox that does not exist, an error is
logged by Dovecot, letter remains at Postfix queue, and no rejection
message to sender (here host is /mail.example.net/):

Thank you for any help in debugging configuration or suggestion to
enhance Postfix/Dovecot parameters.
