Mailbox can't be created
Hi,
I have setup postfix master.cf to use dovecot-lda to deliver (using -m) all messages to PreInbox: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -a ${recipient} -d ${user}@${nexthop} -m PreINBOX
And enabled lda_mailbox_autocreate.
The message I have now it: Aug 27 10:02:29 lda(): Info: msgid=<dae42d0cf57bf4496a3dd53e162f8281@localhost.localdomain>: save failed to open mailbox PreINBOX: Mailbox can't be created Aug 27 10:02:29 lda(): Info: msgid=<dae42d0cf57bf4496a3dd53e162f8281@localhost.localdomain>: saved mail to INBOX
Why wouldn't dovecot itself be able to create mailboxes?
I am using virtual domains and users on a mysql database through postfix and mailboxes saved in MailDir format.
Configuration of dovecot is:
2.2.18: /etc/dovecot/dovecot.conf

I am confused then. /home/vmail/Maildir is 700 for vmail:vmail. If dovecot-lda runs as vmail then there's no problem, if it runs as root it shouldn't face problems either.
How can I determine which user dovecot-lda runs under?
Thanks,

Doh, it says on the line I quoted earlier from master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -a ${recipient} -d ${user}@${nexthop} -m PreINBOX
It runs under vmail:vmail. There should be no problem creating a new mailbox.
Is there a way to understand what's really going on with dovecot?
Thanks,

Strange... postfix 1315 0.0 0.1 121220 7472 ? S 12:59 0:00 pipe -n dovecot -t unix flags=DRhu user=vmail vmail argv=/usr/libexec/dovecot/deliver -f ${sender} -a ${recipient} -d ${user}@${nexthop} -m PreINBOX
I notice that the arg to pipe is 'user=vmail vmail' instead of 'user=vmail:vmail'. This is strange. I certanly have a colon on the master.cf file.
According to 'man pipe' the correct syntax is user=<user>:<group> so I can only assume this is where it's going wrong somehow.

That statement is not correct nowadays as UNIX permissions aren't all any longer. There are tools like AppArmor and in your case with Fedora there is SELinux preventing even actions by root user.
Make sure the SELinux context fits. "/home/vmail" and the subfolder "Maildir" has to be SELinux labeled correctly.
ausearch -m avc

I have no idea how you could get that error message. Looking at the code I don't see any way it could happen.. This error message exists only if the mailbox is tried to be created for a "fail" storage, which you can't really do. I'd maybe try recompiling Dovecot or something.

Add here: i_panic("can't get here");
Then when it crashes, get gdb backtrace as described by http://dovecot.org/bugreport.html
