courier-imap first does a chdir(homedir), then does chdir(maildir)

So how to make this work depends on what authentication module you are using
for courier-imap's authdaemond. You will need to set it up so the account in
question has homedir=/home/postfix/sipse.com.mx/edelacruz and MAILDIRPATH=.
or homedir=/home/postfix and maildir=sipse.com.mx/edelacruz

That's a static default value which is shared by all accounts which don't
have their own explicit 'maildir' setting.

Like I say, this depends on exactly what authentication module you're using.
If you're using authpam / authpwd / authshadow, then the accounts cannot
have their own independent maildir setting, so you should set MAILDIRPATH=.
and the homedir of each account to point to the right place.

However if you're using authuserdb, authmysql, authpgsql or authldap, then
you can configure each account to have both its own homedir and own maildir
setting.

If you're using authvchkpw then you'll have to look at the source code, as I
don't know vpopmail.

Then show your authmysqlrc file, and a sample row from your mailbox table.
