Bug#875954: courier-mta: /usr/sbin/sendmail has wrong permissions
Control: tags -1 moreinfo Hello Bernard, thanks for taking time to file a bug report. On 09/16/2017 03:47 PM, Bernard wrote: > sendmail gets installed with setgid but has to be installed with setuid. Could you please elaborate on why setgid is not enough (with the group set to courier)? The change would grant extra permissions to sendmail, which I'm hesitant to implement. Especially as I can successfully send emails from normal user accounts using sendmail with setgid.

Given the OP reports that sendmail currently has setgit set and that's the case on my box as well, I conclude that Ondřej has properly applied the patch asked for in #812235.
