Where stored my email?

[chrissai]

Hey guys,

I am new to directadmin and extremely new to the linux world... Although I am fairly new to linux bash, I am still able to navigate fairly well. Where is the email stored on the server?
The reason I ask is because I opened my email in my laptop and all of a sudden, 350 or so messages were being downloaded as new messages when in fact I had read these messages anywhere from months ago to days ago, without any rhyme or reason why those messages were chosen. I thought it was just me, then customers started calling me with the same issue.
I logged into my domain through DA and selected to erase all messages from all folders, tried doing a send/recieve in outlook and the emails kept coming. i have no idea what the issue is. I tried for a few hours searching my server for email or any directories where the email would be and I found nothing. Is it hidden? Any help would be great.

maildir or mbox format? Check

ls -a /home/[B]user[/B]/Maildir

and

ls -a /home/[B]user[/B]/imap/[B]domain[/B]

How to convert from mbox to maildir/dovecot and viceversa. How to confirm which is currently being used.

There is already a thread here somewhere for converting to Dovecot but you cannot easily convert back.
