For the most part, I like to use the DEMR as a suggestion and not so much as an automated action. E.g., * Auto-delete= YES,MANUAL,Delay(3),Max(5) Thus the "manual" overrides the delay and max. I then monitor the DEMR to make decisions on manual removal (or perhaps a SET NOMAIL or DIGEST) Others here will recommend other parameters and procedures. /Pete On 1/17/2013 20:02, Marshall, Clinton C wrote: > I am looking for the best way to "tune" a list using error handling and probing. > > I have 26 Lists that have 65'000+ users in them, there is no error checking or probing implemented, whenever one of these Lists are used it just drags the list server down. > > The client has concerns that if the Auto-Delete feature is used a legitimate email address may be removed, but now performance is impacted, ############################ 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
