📝 Preliminary Checks

• I tried searching for an existing issue and followed the debugging docs advice, but still need assistance.

👀 What Happened?

This PR changed the virtual_mailbox_maps to texthash:/etc/postfix/vmailbox. This is only useful for file-account-based systems.

The LDAP integration needs postconf 'virtual_mailbox_maps = ldap:/etc/postfix/ldap-users.cf' but is configured before that, so the correct setting is overwritten by the new code.
This leads postfix being unable process incoming messages.

We need to tweak this line to check for LDAP too or use a different order.

For anyone affected using edge:
Use a user-patches.sh with:
postconf 'virtual_mailbox_maps = ldap:/etc/postfix/ldap-users.cf'

👟 Reproduction Steps

Enable LDAP support via ACCOUNT_PROVISIONER=LDAP.
