Starting with the 5/27 error report, I saw:

> Err First Last  Address
> --- ----- ----- -------
>
>  18 05/26 05/26 xxxxxx xxxxxx <[log in to unmask]>
>                 Last error: 5.1.2 550 Host unknown  

for four users, all on nc.rr.com.  The next several days showed the same
four errors with the first-last dates unchanged.

On today (6/1), the error report showed these 4 users dropped:

>   xxxxxx xxxxxx <[log in to unmask]>
>   Last error was: 5.1.2 550 Host unknown  

Any idea why?  I would have expected them to fall off the report today,
not be dropped.  From my list header:

> * Auto-Delete= Yes,Semi-Auto,Delay(5),Max(500)
