Thank you! I guess I'll need to go back and add ack to each subscriber profile.

SET listname ACK FOR userid@host should do it for a subscriber. Adding to the list definitions DEFAULT-OPTIONS= will not change existing subscribers' options but should effect new and non subscribers. If a subscriber who has this option is not receiving the ACK, then i suspect a problem with their mail system or config. -- Pete ________________________________ To unsubscribe from the LSTOWN-L list, click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTOWN-L&A=1 ############################ To unsubscribe from the LSTOWN-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTOWN-L&A=1
