Answer
GMS Communication Server or GMS List Server has just processed an email message that was returned due to an earlier posting. There have been too many messages returned from this address so the membership of the list has been suspended. This means that this member will not receive any more postings, although they will still be allowed to post to the list.
In this case, the message (id Undefined) related to the list Undefined. The member Undefined has been suspended.
This is the correct result, no action is required by you.
