Can someone advise the best way to convert mailboxes from Mbox to Maildir for Dovecot 2.17 on Ubuntu? Thanks.
mb2md.pl
The program has at least 2 bugs in it:
. If the body has paragraph break (i.e., '\n') followed by the RFC822 keyword 'From', the original message will loose the last half of the message and a phantom message will be created.
Change from my notes:
# if ( /^From /
# -to-
# if ( /^From .*? \d\d:\d\d:\d\d \d\d\d\d/. I never could figure out where the second bug was. This one created some messages with blank subject lines.
Another annoyance was prefixing the newly created mail folders with a '.'
Our site is small (300 users) with 15-20 years of e-mail history. A conservative estimate of the conversion was something like 30 million messages.
Did it work? Yes. I wish I had more time for testing, though. In the end, we fixed the problems on the back side.
I don't need to do anything specific for Dovecot? It'll see the new Maildir account and automatically create the indexes etc?
IIRC it shows you how to use it, you need to indicate where the new maildir is, if you have only a few, do them all manually, if you have many, write a quick bash or perl script to do them, and dovecot will create the indexes when they login.
You will need to tell dovecot to look for the new location though, if your using system users as I suspect you are, then maildir:~/Maildir should do it *but* dont forget to make sure your MTA knows to use maildir as well, I've not worked with system users for a decade, but I think in postfix home_mailbox = Maildir/ will do it, with sendmail its much more tricky and your best sticking with mbox, if exim, NFI - dont use it :)
