Hi, Ok, thanks. I have now got to the point where it works if I start it from a "run as administrator" command shell.
I start Sendmail by "sendmail start" in /etc/rc.d/init.d/". What is the easiest way to automate this without interaction? Ideally from a normal account (which is also an "administrator" if that matters). I want to have a .bat file in the Startup folder that starts Sendmail. /Tomas On Thu, 24 Dec 2020 20:12:17 +0100, Brian Inglis wrote: > > On 2020-12-24 04:17, Tomas By wrote: > > I'm using the Cygwin Sendmail (8.14), and am getting this in the log > > file of a program that is supposed to send an email. > > > > | 451 4.0.0 drop_privileges: setuid(18) failed: Operation not permitted > > | RSET > > | 250 2.0.0 Reset state > > > > Does this come from Cygwin?
