dovecot - Aug 2005 - a few questions about my experience with alpha1

Hi all,

I've just switched from 0.99.10.6 to alpha1 on a Solaris 9 system,
and I have a few questions:

1)  I'm using "verbose_proctitle = yes" but I don't see the
special
username or IP address information in the output of ps.  I've used:

	ps -fu dovecot
	ps -ef | grep dovecot
	/usr/ucb/ps aux | grep dovecot

The process table simply shows the /usr/local/sbin/dovecot, dovecot-auth,
and imap-login processes.  Is there something else that I need to do, or is
there a special way that I should use ps?

2)  After sending dovecot a HUP signal, the logs will report something
like:

	Warning: SIGHUP received - reloading configuration

And everything seems to work fine.  However, *sometimes* after sending
a HUP signal, logging will stop indefinitely.  Has anyone else noticed
anything similar?

3)  We use UW in production, and I'm new to any real use of namespaces.
Almost all of our clients use the root "~/Mail/" to find their folders
(in
$HOME/Mail/) and their INBOXes are located in $HOME/.inbox.  A few people
actually find their folders with the direct path Mail/foldername.  So, I'm
trying to configure Dovecot to work with any of these roots / prefixes:

	~/Mail/
	Mail/
	"" (empty/blank)

I'm using the namespace configuration below, and it seems to work with any
of the above prefixes.  However, the logging that I see makes me wonder if
I'm doing it the best way.  Note the attached log file.  All of this output
was generated with this single IMAP command:

	A01 LOGIN bozo mypassword

Here's my configuration:

 ****************************************************************************
  # Default
  namespace private {
     separator = /
     prefix      location = mbox:%h/Mail/:INBOX=%h/.inbox:INDEX=%h/Mail/
     inbox = yes
     hidden = no
  }
  
  # This is the standard ~/Mail/ namespace that our clients tend to use
  namespace private {
     separator = /
     prefix = ~/Mail/
     location = mbox:%h/Mail/
     hidden = yes
  }
  
  # This namespace is for a few folks who might actually try to
  # directly access "Mail/foldername" -- as if they were accessing a
real
  # filesystem path.
  namespace private {
     separator = /
     prefix = Mail/
     location = mbox:%h/Mail/
     hidden = yes
  }
 ****************************************************************************

So, is this the best way to configure the namespaces for what I'm trying to
accomplish?  And any pointers on how to interpret what Dovecot is working
through with regard to the attached logs would be appreciated.  Notice the
"Sending log messages too fast, throttling.." message (again,
generated
from that single login command).  What might be causing that?

By the way, is there any real difference between the use of %h/Mail and the
possible use of ~/Mail in the location fields above?

Thanks very much!

In most configurations, Dovecot will run the 'imap' program as the user,
so
you'll likely find (as I do) that you want to use:

ps -ef | grep imap

Is it only logging that stops, or does everything else stop as well? How
about sending SIGHUP again, does it fix the problem? Or if not, does
SIGUSR1 fix it (SIGUSR1 only reopens log files)?

The INDEX=%h/Mail/ shouldn't be needed because the default directory is
the same as the directory you gave after mbox:, ie. same one.

Shouldn't you also add :INBOX=%h/.inbox here?

And here?

If it's finding everything correctly, then only problem you have is that
you have set mail_debug=yes. The throttling message comes because imap
process is sending log messages too quickly and Dovecot thinks it could
benefit from having to be stalled for a while in case it's trying to
flood your logs full.

%h works in all cases, ~/ works only after "mbox:" or
"maildir:" string,
so %h is preferred until the location/default_mail_env setting itself is
split to multiple settings (in Dovecot 2.0).
