dovecot - May 2007 - Maildir format migration

Hi all,

I am planning to use dovecot IMAP on my server. Currently it is
running UW-IMAP server with Maildir format storing users' mail. I've
found that dovecot uses different Maildir format from UW-IMAP. Is
there any configuration option for adapting dovecot to use format used
by UW-IMAP?

Thanks a lot.

Tony.

I just finished conversion from UW-IMAP mbox to Dovecot Maildir using  
only Dovecot's "convert" plug-in.  The plug-in worked far better
than
other conversion scripts that I've tried such as perfect_maildir.pl  
and mb2md.  It made the conversion totally automatic as each user  
logged into their account.

A standard UW-IMAP distribution doesn't include support for maildir. Do
you mean you're using that unofficial patch which used UID=xyz in the
maildir filenames? If so, you'll have to change the directory layout to
Maildir++, but otherwise those filenames would work, even though new
UIDs will be given to them unless you write a script that writes them to
dovecot-uidlist file.

Alternatively you could try CVS HEAD version of Dovecot which supports
filesystem layout for Maildirs (mail_location maildir:~/Maildir:LAYOUT=FS), but
then again CVS HEAD is an actual
stable release.

Hi all,

Thanks for the suggestions. I have used patch to UW IMAP to support
maildir, the problem is dovecot uses dot for delimiter, while the
patch for UW IMAP uses slash. So UW IMAP and dovecot have different
directory structure. If this is configurable in dovecot, it would be
nice.

Tony.
