It probably would be more useful to investigate and resolve the actual reason why the report is being generated, than take the sideways idea of just turning it off.  A review of the LISTSERV log should provide some useful clues.

However, there is nothing obviously "wrong" about the report you presented - the date of the most recent error is within five days, so unless something else happens there should not be another report issued for that particular list after tomorrow.  If the SAME report data is presented again on Monday, then there is an issue to be researched.

Or is the problem simply that the list owner just doesn't want to know when someone's email address goes bad?

Good morning all. I know I have asked before, but I have a list owner who continues receiving the following messages on a daily basis for several weeks now. She forwards them to me?!
Is there any way to stop these message from going to her as owner or any way to filter? Thanks again for the help.
Subject: ADMIN-TECH-L: Daily error monitoring report

The following subscriber is currently being monitored:

Err First Last  Address
--- ----- ----- -------
  1 03/24 03/24 Heather Kacmarski <[log in to unmask]>
                Last error: 5.1.1 550 5.1.1 User unknown

Err=   Number of delivery errors received thus far
First= Date first delivery error was received (mm/dd)
Last=  Date of most current delivery error (mm/dd)

Subscribers will  be automatically  deleted from  the list  when delivery
errors have  been reported for a  period of 4  days or more, or  when 100
delivery errors  have been  received, whichever occurs  first. Monitoring
will cease after 5 days without any reported errors.

Note: manually  deleted subscribers may  remain on the  monitoring report
under an alias  address. Such entries will expire eventually;  you do not
need to do anything about them.
