ALERT: exim paniclog /var/log/exim/paniclog has non-zero size, mail system possibly b

Hi,

I don´t know if it is related but after installing new evolution skin I get a new message in my inbox:
ALERT: exim paniclog /var/log/exim/paniclog has non-zero size, mail system possibly broken

Never saw this alert before. Is there a fix/solution for this ?

Kind regards,
Fred
