Getting this error message for several of my contacts. Pretty sure it's a
server problem as I haven't had trouble with them before today

There was a SMTP communication problem with the recipient's email server.
Please contact your system administrator. <abc.123.local #5.5.0 smtp;556 null
byte in data>

Not finding anything in Technet or Google search
Any one familiar with this error?
