exim / cyg_server problem since Windows 10/1809 and 3.0.7 - fixed?

[Henry S. Thompson]

After various upgrades, including switching to cygsshd, the exim service
was failing to launch.  The error log showed

  Unable to setuid/gid to exim. priv_flags: 1

It worked up until recently, using cyg_server as the privileged user.
That user still exists:

> id cyg_server
uid=197611(cyg_server) gid=197121(None) groups=197121(None),114(Local account and member of Administrators group),544(Administrators),545(Users),2(NETWORK),11(Authenticated Users),15(This Organization),113(Local account),4094(OtherSession),262154(NTLM Authentication),405504(High Mandatory Level)

But the setuid/gid error above suggests there's something wrong with it?

So I used the Windows Services tool to change to "Log on as" "Local
System account" (as cygsshd is using), and I _think_ that has fixed the
problem.

Was the the right thing to do?  Should
 /usr/share/doc/Cygwin/exim-4.86-1.README 
and/or
 exim-config

be updated to reflect this?

Thanks,

ht
