Hi,

I just built and installed UW imap-2006 and now I'm trying to set up
some mailboxes to use the mix format.

I tried the usual command:

mailutil copy mailbox "#driver.mix/mailbox.new"

but mailutil complains with "unknown driver".

I did a fast check on the code and see that in linkage.h the mix driver
is not included.

Is this kind of mailbox conversion not supported?

Thanks.

Did you install the imap-2006 version of mailutil?

Are you certain that you checked in the imap-2006 build tree?

It is supported. We use it.

Yes, of course.

$ mailutil
mailutil version 2006.3

usage: mailutil command [switches] arguments
check [-d[ebug]] [-v[erbose]] [mailbox]
...

Yes, the one under ./c-client .

Good to know, has the mix driver needs to be defined as extradrivers
(like mbox)?

Thanks for your quick reply.

Found the problem, mix is not supported under Cygwin, it works fine
under Solaris.

I made a test changing the Makefile for cyg, mailutil compiles fine but
when I run it :

$ mailutil copy -v DenyHosts "#driver.mix/DenyHosts.new"
/home/rberber/mail/DenyHosts [70 message(s)] =>
#driver.mix/DenyHosts.new
[Failed]

even when the result seems fine:

$ ll DenyHosts.new/
total 417K
drwx------+ 2 rberber None 0 Sep 16 01:30 ./
drwxrw-rw-+ 3 rberber None 0 Sep 16 01:30 ../
-rw------- 1 rberber None 416K Sep 16 01:30 .mix450b9a17
-rw------- 1 rberber None 0 Sep 16 01:30 .mixindex
-rw------- 1 rberber None 54 Sep 16 01:30 .mixmeta
-rw------- 1 rberber None 0 Sep 16 01:30 .mixstatus

the original mailbox is about the same size:

-rw------- 1 rberber None 414K Aug 9 13:22 DenyHosts

Anyway, I'll take it is not supported.

One last question: when I convert a mbox file should I create an INBOX
directory?

No, it should not be included in EXTRADRIVERS.
If you include it then things will not work.

I haven't tried using mix under Cygwin; and in general I do not support
Cygwin.

For what it's worth, the result you gave wasn't "fine"; both the index and
status files are empty so it isn't a usable mailbox. So you were getting
the truth from mailutil when it failed.

The problem with Cygwin is that it is neither a complete, nor fully
accurate, implementation of UNIX. For example, Cygwin has Windows style
mandatory locks instead of UNIX style advisory locks; this will bite any
application which implements its locking strategy based upon advisory
locks.

Cygwin is best thought of being a compatibility package that allows the
porting of some UNIX applications to Windows. But as a UNIX environment,
Cygwin will never work as well as a true UNIX system, nor will software
running under Cygwin ever work as well as native software written for
Windows.

There is a specific port of UW IMAP to Windows. This port does not
currently have mix support, although it is not outside the realm of
possibility that a Windows mix driver would be developed in the future.

The Cygwin build specifically sets the drivers that are known to work (or
have been kludged to work) with it. Other local mailbox drivers are known
not to work in Cygwin and are specifically excluded. mix was excluded by
default.

Now that I think about it, mix won't/can't work under Cygwin. Cygwin's
Windows-style mandatory locking (as opposed to UNIX-style advisory
locking) is by itself enough to stop mix from working.

So, if you want mix format on Windows, I'll take that as a request to
build a native Windows driver for mix. As I said in another posting, it
is within the realm of possibility.

The conversion process does this automatically, e.g.,
mailutil copy -kw INBOX #driver.mix/INBOX
is the normal command to convert from a traditional UNIX mailbox INBOX to
a mix format INBOX on UNIX systems.

mix is part of the standard drivers list on UNIX. It is not on Windows
(which includes Cygwin) because there is no(t yet any) supported Windows
code for mix.

So, no, you would not include mix in extradrivers.
