[Dovecot] odd behavior with Dovecot LDA
Okay, to convince myself that quota handling was working okay with Dovecot 1.0-rc27 on Solaris 10, I tested sending a message to an account that was purposely over-quota. The account in question had a vacation message set up.
For the first test, there was no $HOME/.imap directory at all. I received the vacation message, but the message which was supposed to be delivered locally queued in Postfix (temporary failure).
For the second test, I created $HOME/.imap and $HOME/.imap/INBOX directories with the owner and group set to that of the user (just to make sure the code handled things the same). Again, I received the vacation message, but the message which was supposed to be delivered locally bounced back to me after Dovecot LDA crashed:
<syst0005@peridot.tc.umn.edu>: Command died with status 139: "/opt/dovecot/libexec/dovecot/deliver -f "$SENDER"". Command output: Segmentation Fault
It appears that Dovecot LDA assumes that if .imap/FOLDERNAME exists that the index files must also exist.. I wonder what other assumptions might cause segfaults.

Could you get gdb backtrace? Although it's possible that it's already
fixed. I can't reproduce any out-of-quota problems with current CVS
code.
You could also try running it manually:
echo hello | deliver -d username

In rc28 or the upcoming rc29?

I have been trying to get a core, but haven't succeeded thus far. I have set "mail_drop_priv_before_exec = yes", but I'm not sure this applies to the LDA... I ran a find to locate the core, but there isn't one. I do have "ulimit -c unlimited" in effect, too.
You could also try running it manually:
echo hello | deliver -d username
Doing so yields this error:
Mar 28 13:41:37 myhostname deliver(myuser): net_connect(/var/opt/dovecot/run/dovecot/auth-master) failed: No such file or directory
Not sure how my environment is different than when Postfix calls deliver...

mail_drop_priv_before_exec doesn't affect deliver. Also I don't know
if Postfix preserves ulimits.
You could also try running it manually:
echo hello | deliver -d username
Doing so yields this error:

Is the deliver binary the same? What is the correct socket path?
Maybe they're using different config files.

There is only one deliver binary on the host in question.
Here's our current dovecot -n output for the host in question:

Oh. So you're not using the -d parameter with Postfix. Then run only:
echo hello|./deliver
as the user who you want to deliver the mail to.

Thanks. Although I found and fixed this one a few days ago :)
