This is greylisting response, some servers employ greylisting to lessen spam

hi mate

thanks for the response.

how would i go about fixing this?

There is nothing you can do. Remote server could whitelist your server but it is up to them. Otherwise your messages will be retried in few minutes and be delivered, not much to worry about.
