Oops. Might've been the 11.04 version then. I'm getting
Nov 6 06:43:39 wikiop postfix/pipe: B6C752A1E7B: to=<email@example.com>, relay=maildrop, delay=67760, delays=67760/0.02/0/0.08, dsn=4.3.0, status=deferred (temporary failure. Command output: ERR: authdaemon: s_connect() failed: Permission denied /usr/bin/maildrop: Unable to open mailbox. )
a fair amount. I found it on google and it said that its being run as the vmail user so I changed file permissions on it.
Somehow another email decided "Hey I'm working! Look!" so I loaded it and it works fine. I removed the mailbox for the above user and then sent it an E-mail and it created it and it worked. However, the Sent folder, Junk folder and Drafts folder are not there.
