Hello Ired support 
Unfortunately, i needed to launch an apt-get upgrade on my mail server, then reboot it .
Since then, I'm not able to receive/send mail.
Here is the /var/log/mail.log error

Can my apache2/php5 can be too "new" for my 0.8.5 IredMail version ?
Can an update to 0.8.6 can help me get my mailbox working again ?
Everything seems to work perfect except sending and receiving mails .... 
Will appreciate help here a lot
