The word 'namespace' does not appear in any file within the tree of
/etc/dovecot/  This was a suggestion that was offered to me from the Postfix
list when I was cleaning up my postfix installation, but I wasn't certain of
which file it should be in (or if it even matters from the software
perspective). I'm curious how so many other users could have gotten the
HOWTO to work for them without having to add this.  This is maybe day 4 of my
experience with dovecot, so I am very cautious, but I can try adding this to
10-mail.conf and restart the service...

According to the mail.log, Postfix handed dovecot a message.  Might have been
the test email from a couple days ago.

Hey, there is content in the directory tree of /var/mail/vhosts/example.com/bob/
That was empty before.

/var/mail/vhosts does exist and it's owned by vmail, which was a user and
group that was created during the process.

drwxrwsr-x  3 vmail vmail 4096 Dec 11 12:53 .
drwxr-xr-x 13 root  root  4096 Nov  7 18:39 ..
-rw-------  1 root  vmail    0 Dec 11 12:53 root
drwxr-sr-x  4 vmail vmail 4096 Dec  8 00:14 vhosts

Permissions seem to be good enough for writing to it. The privacy and
permissions of the subdirectories are good too.  I'm not entirely certain
why an addition mail user vmail when I already have a user called postfix and
dovecot.  Anyway, the directory has been written to by dovecot since the
subdirectories have changed since adding the change to 10-mail.conf and starting
the server

And guess what, I can log into squirrelmail's interface just fine.  No more
dropped connection to the IMAP server.

And now that the panic is over, I'd like to get smart on dovecot.

Wow, you actually need to set this namespace in 10-mail.conf

Well we are fixed. I thought it wasn't that.

Try adding the namespace restart and tell me what it does.

I added the namespace to 10-mail.conf (that was the only change I made today). 
And when I turned on dovecot (it had been stopped since yesterday) the message
immediately passed through.  So yes, the namespace suggestion from the postfix
guy worked.  I've been reading up on namespaces since then.  I have a
feeling that there are some wonderful things I can do with this package.

In some ways, the parts of the documentation seem vague and inexact so I guess
it will have to grow on me.


http://wiki2.dovecot.org/Namespaces

"If the configuration doesn't explicitly specify a namespace (as was in
v2.0 and older) a default namespace is created automatically."

I think this might have been what was going on.  The HOWTO I read may have
already gotten stale and Dovecot has since grown.
