I use Virtualmin to manage my server. I have somehow screwed up the configuration and mail is not being delivered to my mail boxes. I'm desperate to solve this as my mail server is toast. My tail /var/log/procmail.log shows
procmail: Program failure (255) of "/etc/webmin/virtual-server/lookup-domain.pl"
procmail: Unable to treat as directory "/home/mike/Maildir"
procmail: Lock failure on "/home/mike/Maildir.lock"
procmail: Error while writing to "/home/mike/Maildir"```
