Immediately upon the entry of an order or judgment the clerk of the district court, or magistrates division, shall serve a copy thereof, with the clerk’s filing stamp thereon showing the date of filing, by mail on every party affected thereby by mailing or delivering to the attorney of record of each party, or if the party is not represented by an attorney, by mailing to the party at the address designated by the prevailing party as most likely to give notice to such party. The prevailing party, or other party designated by the court to draft an order or judgment, shall provide and deliver to the clerk sufficient copies for service upon all parties together with envelopes addressed to each party, as provided above, with sufficient postage attached, unless otherwise ordered by the court. The clerk shall make a note in the court records of the mailing. Such mailing is sufficient notice for all purposes for which notice of the entry of an order is required by these rules; but any party preparing a proposed order or a proposed judgment shall in addition serve a copy on each party in the manner provided in Rule 205 for the service of papers. Lack of notice of entry of an order or judgment does not affect the time to appeal or to file a post-judgment motion, or relieve or authorize the court to relieve a party for failure to appeal or file a post-trial motion within the time allowed, except where there is no showing of mailing by the clerk in the court records and the party affected thereby had no actual notice.
