Plesk attempting to deliver emails locally even though email service is disabled globally.

On one plesk server I manage it does no emails except for password reset.
The client has over 100 wordpress sites on this server.
Password reset emails are not going out and local delivery is being attempted even though no clients use that plesk server for email services.
This is despite the fact that in plesk we have disabled email management functionality

Upon checking the postfix main.cf file I found that plesk was still loading all the domains into the virtual configurations

virtual_mailbox_domains = $virtual_mailbox_maps, hash:/var/spool/postfix/plesk/virtual_domains
virtual_alias_maps = $virtual_maps, hash:/var/spool/postfix/plesk/virtual
virtual_mailbox_maps = , hash:/var/spool/postfix/plesk/vmailbox

It appears that plesk added these during install which is expected. But didn’t remove them when I disabled plesk from managing the email services.

So I have simply commented them out and restarted postfix.
