Hi,
Since the 23rd of March, we encounter mailbox corruption for some users (15 out of 5000) using POP mainly via Thunderbird. Symptoms are :
-users can login but fail to receive new mails and fail to read their inbox -Dovecot.log : ar 29 11:00:06 Error: POP3(user_login): Couldn't init INBOX: Mailbox isn't a valid mbox -The mailbox start with either 'FFrom or 'FrFrom'
We can temporarily fix the issue by manually editing the mailbox so that it begins with a proper 'From'. For some users, the problem reoccurred after we apply this workaround. I have to mention that this server has been running fine since almost a year with the current hardware and software configuration.
Does anybody has an idea regarding this issue?
Many thanks
Henri
