Hi

I have a virtual-email hosting set up with PostgreSQL 8.2, postfix-pgsql, on
Ubuntu 6.10 that i really wanted to get working with maildir, so I can use
courier imap with it cleanly. However, when I append the trailing / to the
maildir and absolute_maildir fields of the database row, i start getting
very strange errors. Has anyone got any ideas? I do remove the mbox file
before trying the maildir way. I saw some very old messages saying that
there was an incorrect error message somewhere.

Thanks!
bill
