Send ok, receive not anymore (but used to)

[mattewre]

Hi,
I'm experiencing a problem with mail.
I can send mail correctly, but I can't receive from few weeks. Everything was working fine on every domains (so I can exclude a wrong configuration of DNS on these).
I would like to receive some tips to start to fix the problem.
(there are not important mail in the mailboxes, I can delete everything about mail if needed. Important data are about web hosting instead).
Thank you

New Details, when I send a mail to any domain running on the server, I get this response:

<info@domain.eu>: temporary failure. Command output: Can't open log file

Ssh into your server and go to the /var/log folder and make sure that file is the folder. Then make sure permissions are set properly. (User=vmail Group=Mail CHmod=0660)
