-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Anyone out there know of a tool that can convert a Cyrus MailDir format to Dovecot mbox? I have a user that I need to move over from a mail server running cyrus using MailDir format. At first I told him to setup second account with Thunderbird to our mail server and then use Thunderbird to move the messages over. But he has over 100K messages so not as easy to do. Is there a tool out there for doing this sort of conversion? I tried to simply cat all the messages into a single file, but just got a "Not valid mbox format" when I tried to read the mail folder. - -- C. J.

From there use some maildir to mbox conversion tool (e.g. Dovecot's convert- tool). -------------- next part -------------- A non-text attachment was scrubbed...

Timo,
Thanks. The cyrus2dovecot looks to have worked. So if I understand
the process I now just move the MailDir folder that was created to the
users home directory on our mail server. I will try the dovecot convert
plugin. Just make sure I'm doing this correct in the config file:
mail_location = mbox:~/:INBOX=/userM/mail/%u
protocol imap {
mail_plugins = convert
}
plugin {
convert_mail = Maildir:~/Maildir:INBOX=/userM/mail/%u
}
Is this correct? The example on the website only shows how to convert
from mbox to MailDir.

The UIDs aren't preserved, but everything else seems to be. My MUA (Gnus with the nnimap backend) uses custom flags to store state and all of that state was preserved. Losing the UIDs in Gnus' case, only meant that the cached article information was useless, and that I would have to freshly download everything I wanted cached. And it also turned out to be mostly irrelevant, since the folder structure changed with dovecot. The only folder for which I could have preserved cached information would have been the INBOX.
