A coworker, who manages our Postini incoming mail accounts, spoke with Postini. They told him my complaint has become rather frequent. Their solution is to use Postini for outbound mail as well as incoming mail. On the one hand, all our MX records (aspca.org) are on the Postini system. On the other hand, it ain't cheap! (Still "cheaper" than "vanishing", though.) -------------------------------------- Richard McClary, Systems Administrator ASPCA Knowledge Management 1717 S Philo Rd, Ste 36, Urbana, IL 61802 217-337-9761 http://www.aspca.org
