You can't, as it is the clients task to retry with the remaining recipients and it is no hard error. > Q3 = is there danger in increasing limit so senders emails are delivered as > they should be ? What other options are there ? Find the error. But guessing from the subject of the mail in question you really want some specialized mailing list software like Mailman for this task.
