I'm using the Cygwin Sendmail (8.14), and am getting this in the log

Does this come from Cygwin? It would be odd if it is from the program.
There is no user 18. The Windows user id's (I think) are 500, 501,
1000, 1002, 1003.
$ getent passwd 18
SYSTEM:*:18:18:U-NT AUTHORITY\SYSTEM,S-1-5-18:/home/SYSTEM:/bin/bash
What is the simplest solution?
I had it working before I reinstalled, but I tried many things, most
of which I do not want to repeat.
Process or program may need to be run elevated with admin privileges,
or configured to not require them if that is even possible.
The easiest way to do that I have found is to create a Windows task to
run elevated (with highest privileges) under user SYSTEM and run a
shell invoking a shell script.
The task may then start up Cygwin services to run elevated under user
SYSTEM or however each is configured.

The easiest way to do that I have found is to create a Windows task to run

The task is normally run at system startup, and the shell script uses cygrunsrv
to start all services, but could be run at user login instead I believe, or
whatever other approach you have to execute scripts as elevated admin processes.
