Package: courier-mta
Version: 0.75.0-10
Severity: important
Tags: patch
Hi Ondřej,
When I try to execute /usr/sbin/sendmail, I get
# sendmail
setuid/setgid: Operation not permitted
Changing the permission from 4755 to 2755 (setgid instead of setuid bit) solves
the issue.
Patch attached (untested, but fix seems obvious). I can push to collab-maint
if you approve the patch.
Bye
Willi
