[Dovecot] error when using dovecot-lda as non root (vmail) user
Hello,
after finally having managed to setup up dovecot with virtual users and
public folders I tried to get it connected to postfix.
The problem is, that I can't get postix to deliver mail via dovecot-lda.
After some testing it seems to come down to dovecot-lda behaving
different when called as root then when called as user vmail.
Basic setting:
- dovecot 2.1.1
- all mailboxes owned by user vmail (using mail_uid and mail_gid)
Test 1:
as user root:
/usr/libexec/dovecot/dovecot-lda -d ahelmcke < some_mail
working as expected; some_mail gets stored in users INBOX
Test 2:
same command executed as user vmail. dovecot-lda terminates immediately.
syslog-output with mail_debug = yes:

So, change reverted (excerpt from doveconf -n): mail_location = maildir:/home/mail/user/%u namespace inbox { inbox = yes location prefix = INBOX/ separator = / type = private } Now dovecot-lda is complaining about duplicate namespaces (still only when run as vmail; run it as root and it is working): Apr 19 17:58:07 elablnmail02 dovecot: lda: Debug: auth input: ahelmcke Apr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Debug: Effective uid=494, gid=491, home=/home/mail/user/ahelmcke Apr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Debug: Namespace inbox: type=private, prefix=INBOX/, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/home/mail/user/ahelmcke Apr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Debug: maildir++: root=/home/mail/user/ahelmcke, index=, control=, inbox=/home/mail/user/ahelmcke, altApr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Debug: Namespace dummy: type=private, prefix=, sep=/, inbox=no, hidden=yes, list=no, subscriptions=yes location=maildir:/home/mail/user/ahelmcke/public/ Apr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Debug: maildir++: root=/home/mail/user/ahelmcke/public, index=, control=, inbox=, altApr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Debug: Namespace : type=private, prefix=, sep=, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/home/mail/user/ahelmcke Apr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Debug: maildir++: root=/home/mail/user/ahelmcke, index=, control=, inbox=, altApr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Error: user ahelmcke: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" Apr 19 17:58:07 elablnmail02 dovecot: lda(ahelmcke): Fatal: Invalid user settings.
