Hi all,

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? 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.

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.

/Tomas
