Maildir: no such file or directory

Hello,
My server was working just fine for months but suddenly i can't receive my mails anymore. My mail client is giving me the message "Maildir: no such file or directory".
I had a look back to http://www.howtoforge.com/perfect_setup_debian_sarge_p4 and saw that
"
You do not have to do this if you intend to use ISPConfig on your system as ISPConfig does the necessary configuration using procmail recipes.
postconf -e 'home_mailbox = Maildir/'
postconf -e 'mailbox_command ='
/etc/init.d/postfix restart "

What i really don't understand is that inside my /home/www/web12/ folder i have a Maildir alias which is pointing to himself (Maildir -> /home/www/web12/user/web12_jeanjacques/Maildir) and all the emails are arriving inside /home/www/web12/user/web12_jeanjacques/.

This is my mail.err log:

Jan 20 09:22:27 hulk courierpop3login: LOGIN FAILED, ip=[::ffff:127.0.0.1]


I don't really where to look at, as this error arrived suddenly.

Your help would be really appreciated.

Best regards,

Below here is my postfix config file:

Hello Till,

No apparently i changed nothing before the account stopped working, this is really why i don't understand what's going on.
This user is the administrator of the website so apparently the alias is normal.

The emails are arriving inside /home/www/web12/user/web12_jeanjacques/ and NOT in /home/www/web12/user/web12_jeanjacques/Maildir

if i do a "cd Maildir" the bash is returning me an error message telling me that the folder doesn't exist...

 

Apparently the problem is coming from procmail.
I have deleted the alias and recreated a Maildir folder. but now i have this error message Maildir invalid "no 'cur' directory.

Have you ever seen this ?

 

Do you think that it's safe to manually create the Maildir using the command maildirmake ?

 

Hello Till,

Thank you now, everything is working properly.
I had to re-create the Maildir folder using the maildirmake command.

Best regards,

JJ
