[Dovecot] Calling dovecot-lda from maildrop/shell

[Florian Lindner]

Hello,

I want to make final delivery for some of my mailboxes using 
dovecot-lda, since I'm interested in using sieve. My usual MDA which is 
called from postfix is and will be maildrop.

First try was to call dovecot-lda from command line:

/usr/lib/dovecot/dovecot-lda -d spam at xgm.de < testmail

which gave return code 75 (EX_TEMPFAIL) and logged:

dovecot: auth-worker(3533): mysql(localhost): Connected to database 
system
dovecot: imap-login: Login: user=<spam at xgm.de>, method=PLAIN, rip=::1, 
lip=::1, mpid=3535, secured, session=<jwXWP3HrwgAAAAAAAAAAAAAAAAAAAAAB>
dovecot: imap(spam at xgm.de): Disconnected: Logged out in=91 out=830
dovecot: lda(spam at xgm.de): Error: user spam at xgm.de: Initialization 
failed: Namespace '': Mail storage autodetection failed with 
home=/home/flindner/Mail/spam
dovecot: lda(spam at xgm.de): Fatal: Invalid user settings. Refer to server 
log for more information.

My userdb/password is like that home == maildir == 
/home/flindner/Mail/spam  (without prefixed "maildir:"). It works fine 
for dovecot-imap, it detects that spam is a maildir.

I've also tried prefixing home and or maildir with "maildir:" or 
calling: HOME=maildir:~/Mail/spam /usr/lib/dovecot/dovecot-lda < 
testmail which gave:

dovecot: lda: Error: user flindner: Relative home directory paths not 
supported: maildir:/home/flindner/Mail/spam
dovecot: lda: Fatal: Invalid user settings. Refer to server log for more 
information.

What is the problem with the LDA here?

Thanks,
Florian
