How to fix imapd No such file or directory?

[Icon]

Hello, all
I tried to install postfix on Ubuntu 11.10 by tutorial http://www.howtoforge.com/virtual-us...l-ubuntu-11.10
but got an error quota patching http://www.howtoforge.com/forums/showthread.php?t=55770
I don't know how to fix so tried to go without it
But now mailx user@example.com gives this error:

Feb 27 12:31:01 example postfix/pickup[1466]: 927E14298B: uid=0 from=<root>

/home/vmail folder's owners root and group vmail where is users vmail and postfix
When trying to login by squirrelmail it gives out Conenction refused by IMAP server and /var/log/mail.log says

Feb 27 12:11:24 example imapd: Connection, ip=[::ffff:127.0.0.1]
Feb 27 12:11:24 example imapd: chdir example.com/user/: No such file or directory
Feb 27 12:11:24 example imapd: user@example.com: No such file or directory

If I create /home/vmail/example.com/icon by myself squirrelmail says

Query: CREATE "INBOX.Sent" Reason Given: Cannot create this folder.

May it be because of not quota patching? and how I can fix this at all?

Looks as if amavisd isn't running. Please restart it.

Please add mail.example.com to the mydestination line in /etc/postfix/main.cf and restart Postfix.

Was it there all the time, or did you recently add it without restarting Postfix? Do you still get the error in your mail log?

It's here from beginning
I restarted it many times, even reboot server
And still same error
I read in some forum that it's because of exceeding quota limit, that returned me to think reason is in no quota patch

[falko]

Did you use the correct quota patch for your Postfix version?

No, I said i didn't used any quota patch because of this http://www.howtoforge.com/forums/showthread.php?t=55770 error
Postfix 2.8.5
Quota patch postfix-vda-v10-2.8.5.patch

[falko]

Did you follow the tutorial as closely as possible? For example, did you disable dash? I've never had any problems building Postfix with the quota patch.
