Hello, I am looking for the best way to "tune" a list using error handling and probing.

The client has concerns that if the Auto-Delete feature is used a legitimate email address may be removed, but now performance is impacted, regards Clinton Marshall Cloud Operations Telstra Corporation Limited ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1
