Configuration for postfix and courier
 

I followed the steps found here:
http://flurdy.com/docs/postfix/

On Ubuntu Edgy.

I can see SquirrelMail from a browser. When I log in to SquirrelMail my mail.info shows a successful login but the browser shows:
ERROR: Connection dropped by IMAP server.
Query: SUBSCRIBE "INBOX.Sent"

So, I telnet into 127.0.0.1 143, and try a couple things (username = mark):
a list "Mail" "*"
a OK LIST completed
a list "virtual" "*"
a OK LIST completed
a list "mark" "*"
a OK LIST completed
a create inbox
a NO INBOX already exists!
a list "inbox" "*"
* LIST (\HasNoChildren) "." "INBOX.Sent"
a OK LIST completed
a create INBOX.Trash
a OK "INBOX.Trash" created.
a list "inbox" "*"
* LIST (\HasNoChildren) "." "INBOX.Trash"
* LIST (\HasNoChildren) "." "INBOX.Sent"
a OK LIST completed
a create INBOX.Drafts
a OK "INBOX.Drafts" created.
a subscribe INBOX.Sent
* BYE [ALERT] Fatal error: No such file or directory
Connection closed by foreign host.

If I try subscribe INBOX I get the same answer.

Now... if I go to to browse the mail folder, I get this:
mark@linux800:/var/mail/virtual/mark$ ls -a
. .. .Drafts .Sent .Trash
mark@linux800:/var/mail/virtual/mark$

I created the 'mark' folder in virtual, and assigned virtual as the group and owner.

Now... the HowTo said something about things running chrooted, and this could cause a problem with Debian based distros (Ubuntu is Debian based). Could this be the problem, that Courier can't do what it needs with file/folder access?

I've also tried Evolution to connect, but I'm assuming that if I can't subscribe via telnet, no other client can either. But I did also try Evolution using POP, and that failed.

Please help.

Please send an email to that user before you try to log in. Maildir and its subdirectories will be created automatically when the first email arrives.
