An OOO may be generated by the MTA, but most of the problematic OOO messages that we see are sent by the recipient's MUA. Before he left on vacation, Joe User created a filter rule in his email client which sends his vacation auto-reply message to the 'From:' address on every message he receives, regardless of envelope-sender address on the message, or the number of vacation auto-reply message that might have been sent to a given address in the last hour, day, or week. And since his email client is configured to check for new mail every minute, and he is subscribed to several active lists, and his subscription is set to MAIL on every one of those lists, his unattended workstation now becomes a source of OOO spam. -- Paul Russell, Senior Systems Administrator OIT Messaging Services Team University of Notre Dame [log in to unmask]
