Hi Sonia, Notice that it's a 4xx return code, meaning its a transient error.
My take is that the SLUG mail servers have greylisting enabled. Any new SMTP sessions would be placed on hold for a specified amount of time (normally 20 minutes?) The whole purpose of the exercise is to slow spammers down.
