I'm using postfix for mail delivery and dovecot for mailbox access imaps pop3s.
Postfix resolves, verifies and overwrites users' addresses by numerous subtle LDAP queries. However users are visible as local ones (openldap, pam, nss) in the sense I can run
id' orfinger' queries and receive replies.Dovecot handles all mailboxes over imap/pop correctly with no additional configuration for LDAP. Just (10-mail.conf):
mail_location = maildir:/mailboxes/%u
and it works fine.
Because I'd like to use pigeonhole I'm trying to make local delivery via dovecot LMTP (https://wiki2.dovecot.org/HowTo/PostfixDovecotLMTP). I've configured the socket and added to `/etc/postfix/main.cf' the line:
mailbox_transport = lmtp:unix:/var/spool/postfix/private/dovecot-lmtp
I think that id dovecot handles mailboxes correctly over imap/pop it can easily find the users and their mailboxes so it doesn't need any additional configuration for LDAP. Unfortunately it doesn't work and results in:
Undelivered Mail Returned to Sender: User doesn't exist! :-(
What's the thing I've missed?

If your usernames do not have a domain, you need to configure auth to lookup users by local part only.
Depending a bit on situation, sometimes it's better to do
auth_username_format = %Ln
sometimes it's better to configure the passdb itself.
