Received email is written in wrong mailbox

I have a view web users with several email accounts.
Something went wrong with the email accounts. I now get emails for web12_xyz in web10_zyx.

The mailboxes do not even have the same name.

Does anyone know where the problem lies?

Thanks for any advice!

 

What's in your mail log?
What's in /etc/postfix/virtusertable?

 

Where can I find the mail log?

In /etc/postfix/virtusertable it is written right. web12_xyz. but it still get's written in web12_abc

 

from the log:

Jul 3 15:25:27 vs186100 ipop3d[14290]: pop3 service init from 213.55.131.22
Jul 3 15:25:28 vs186100 ipop3d[14290]: Mailbox vulnerable - directory /var/spool/mail must have 1777 protection
Jul 3 15:25:28 vs186100 ipop3d[14290]: Login user=web4_abc host=[213.55.131.22] nmsgs=1/1
Jul 3 15:25:29 vs186100 ipop3d[14290]: Mailbox vulnerable - directory /var/spool/mail must have 1777 protection
Jul 3 15:25:29 vs186100 ipop3d[14290]: Logout user=web4_abc host=[213.55.131.22] nmsgs=1 ndele=0​

web4_abc is where it should go. it then gets saved into web10_xyz but that is nowhere in the log.

No, neither web4_abc nor web10_xyz are catchall acounts.

 

Please run

Code:

chmod 1777 /var/spool/mail

and try again.
