Hello,
I've beening using Dovecot with:
mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u

Now i wanna switch to Maildir, because it supports more stuff, like quotas and so on. I have setup Dovecot like this: mail_location = maildir:~/Maildir, also I have converted the old mails to Maildir type of mails and worked perfectly, but no new mails. I know something is missing, but I have never setup Dovecot with Maildir, so please if you know, help me out with this.

Perhaps you forgot to tell whatever program delivers your mail about your new mailbox format and location? If this is the case, it would keep delivering new mail to the old location.

You will probably get a way without the mail_location setting, since dovecot is pretty good at finding mail by default.

I think if I dont set the mail_location it wont work, or it will automatically set it to "mbox".

There has to be proper settings for dovecot, just dont know them myself.

As I said, you shouldn't need to set it.

Is there any mail being delivered in maildir? Look in ~/Maildir/new

I have tried to disable mail_location, and again it works, sees the mails like in Maildir format, but dont receive new mails.

Dovecot has to be set how to read the new incoming mails, but dont know how to really set this.

It should be I think something like this:

maildir:~/Maildir::INBOX=/var/spool/mail/%u

I've never had to change dovecot's config.

Last time - what's in ~/Maildir/new?

In ~Maildir/ is what normally is in ~mail/. There are the mails, mail folders and so on. New mails normally would go to /var/spool/mail/username, then depending on what the user does, goes into mail/ in folder "INBOX" or depending on the user, goes into some other folder.

But all of this works in form of "mbox" style, meaning the mails that are deposited in mail/ folder. The to switch from "mbox" style to "Maildir" first you would need to convert the old mails from mail/ folder to Maildir/, which I have done and it works. All the mails are there, everything works, just getting new mails doesnt work.

Man there is nothing delivered to Maildir, otherwise I would ask why Im not getting new mails, would I?

If nothing is being delivered to the Maildir, it's nothing to do with dovecot - it only serves up what's delivered by your delivery agent.

What is you mail setup - what MTA do you use, etc?

Im using postfix with Mailscanner. I was thinking of the same idea, just dont know how to fix it

In main.cf. Note the closing "/"

Ok cool, thats what Im talking about. This worked, and wanna thank you very very much

You're welcome Robert.
