I use Postfix and Dovecot. Two days ago /var/spool/clientmqueue started filling up with messages. I have seen one or 2 messages a month there but today there were nearly 2,000. They do not appear to be spam messages. I don't know if these issues are related but I have also noticed these issues as well: - init runs a LONG time after a reboot - It takes a long time to connect via SSH Any ideas?
