Looks like you're being overloaded by mails, and your server can't follow (I guess it's a low-end CPU, or doesn't have enough RAM, or both). You should first try to identify where those mails are coming from (tailf /var/log/qpsmtpd/current | grep logterse | tai64nlocal). Then, either fixe the machine which is sending too much mails, or block it if it's not under your control
