Thanks for everybody's tips on the mbox to maildirs converter. I was unaware that Maildirs was a common format not specific to dovecot, so I was searching using a dovecot keyword.

I'm having this problem now with inboxes. I want to use maildirs, but my mail is delivered to an mbox. I can't seem to get dovecot to recognize the inbox location. Is something like:

maildir:%h/Maildir:INBOX=/var/mail/%u impossible to use?

What I'm trying to do is slowly merge people from mboxes to maildirs, so I have to use the passwd file per user maildirs settings with some sort of recognizeable inbox.

I'm using sendmail as my mail server. Do I have to tell that to put the mail in the right inbox format?

My first post on here:

I found this old thread and am trying in vain to achieve the same. In short should something like the following work?:

location = maildir:/home/virtual/%d/home/%n:INBOX=mbox:/home/virtual/%d/var/spool/mail/%n

I am trying to have my user's use MailDir within their own home folders but Dovecot needs to read a standard MBOX format incoming mail spool file.

This seems a fairly reaonsable requirement since lots (most?) delivery programs are used to delivering to standard mbox files.

An auxillary question: is it possible for Dovecot to 'slurp' those mbox files into a local maildir INBOX folder to keep things fast?

Thanks for any help from an enthusiastic dovecot newbie! Daniel
